Cats, houseplants and grass – why does my cat get the munchies?
Cats always seem to want what they are not supposed to have – and houseplants are no exception. Cats are carnivores- why would they want to nibble on your spider plant or the lovely flowers your significant other just gave you?
In the wild, cats eat many small meals consisting of rodents, birds, bugs, and other small creatures. Most of these prey animals have intestines full or seeds, grains, and other vegetation. Cats enjoy eating the intestinal tract (yum!!!) and consequently about 10% of their calories come from non- meat sources. So, cats can digest some plant material. Cats also need some non-digestible fiber in their diet to help with normal stool production.
Cats, like infants and toddlers, often investigate things by chewing on them. New plants or flower arrangements are loaded with intriguing new smells. Your cat will chew on them in part to get more information, and also to test them out as a food source. Cats have an interesting organ called the vomeronasal organ on the roof of the mouth behind the front teeth. It is in essence a “super nose”. Cats may wrinkle their upper lips, start nibbling an item, and get interesting smells to that organ. Some cats love the texture of certain plants and will chew on them for fun. Cats that are either highly intelligent and need to check everything out, or cats that are bored and have nothing to do are more likely to chew on plants. Younger cats are also more likely to chew on both plants and other stringy items such as cell phone charger cords and ribbons.
Some people think that cats chew on grass to make themselves vomit. As far as we know, cats are not bulimic! However, cats do often vomit after chewing on grass and other fibrous plants. This may have evolved as a means of reducing parasite numbers in the intestinal tract. Cats that are feeling nauseated may be more likely to chew on fibrous plant material. Some cats do develop pica, which is eating non -food type materials. This can occur from anemia. Anemic cats are low in iron, and they may eat soil or cat litter due to their bodies attempt to get more iron to correct the anemia. Some cats need more oral stimulation and chewing on plant material fulfills that need.
Try offering safe plant materials. Commercial pots of cat grass are available such as “Kitty greens”, or home made versions can be grown using grass seed and potting soil. Spider plants are also safe for cats to nibble on.
The biggest worry we have with cats eating plants or flowers are lilies. Nibbling even a small amount of the leaves or petals can cause severe kidney failure and death in cats. Keep lilies out of your house if you have cats! If your cat does eat or have any contact with lilies, call your veterinarian immediately. Rapid medical intervention may save your cat’s life.
Many cats find potting soil a lovely form of cat litter, and may enjoy digging in and even eliminating in your houseplant pots. You can make the soil less attractive by placing screen door mesh over the soil (cut to allow room for the plant). Your cat cannot dig in the soil, but water will easily pass through. You can also use gravel on top of the potting soil to make the texture less attractive to your cat.
Don’t forget about catnip! One-half to two- thirds of cats enjoy catnip “recreationally”. Nepetalactone is the chemical that causes the rolling around, licking, drooling, and mild sedation in cats. Some cats will get hyperactive or aggressive especially if they ingest larger amounts, and some cats are not affected by the nepetalactone. Many people grow catnip for their cats as a safe option for their plant snacking cats. Bon appetit!
Cats and Easter Lilies – a Deadly Combination!
Easter lilies, found in bouquets and potted plants particularly this time of year, are extremely toxic to cats. Ingestion of any part of the lily causes kidney failure within 36-72 hours.
“Cat owners need to be aware that the consequences can be devastating, even fatal, to our feline family members”, states Dr. Cindy McManis of Just Cats Veterinary Services in The Woodlands, Texas. “Though not as popular this time of year, other species of lilies such as Tiger lilies, Day lilies, Stargazer lilies and Oriental lilies are also extremely toxic.”
Symptoms include lethargy, loss of appetite, drooling and vomiting. Delay of treatment for over 18 hours will likely result in kidney failure and a high risk of death. Treatment includes evacuating and protecting the stomach and intestines from any absorption of the toxin and administering intravenous fluids. Dr. McManis notes that other species of animals such as dogs and horses are not known to be affected. Peace lilies and calla lilies are not in the same genus but can cause minor mouth and gastrointestinal irritation. Due to these risks, cat owners are encouraged to avoid placing lilies anywhere where cats reside.
In addition to having your regular veterinarian’s office number readily available, owners should have the number for Animal Poison Control, (888) 426-4435, accessible.
If your cat exhibits any of the symptoms noted above or if you suspect that your cat has ingested any part of an Easter lily seek veterinary care immediately. With prompt treatment, full recovery is possible.

… Two Toxic Plants: Helping your Cat Avoid the Emergency Room this Holiday (pt. 2)
If you missed out on the previous part:
Many people decorate their homes with festive holiday plants that are gorgeous to look at, but may be deadly if eaten. In addition, many are busy baking and cooking in preparation of big family meals together. Since we’re so busy, sometimes we may not notice if our mischievous cat is trying to snack on something she shouldn’t.
Here are some of the top holiday items that cats love to eat (but shouldn’t!):
Plants
First of all, it is important to note that even non-toxic plants can cause coughing, choking, stomach upset or mild vomiting. Sometimes a leaf can even become lodged in a nostril or scratch or irritate an eye. If your cat eats a plant and needs to seek medical attention, it is always a good idea to bring the plant that was eaten with you to the vet – that way if you are uncertain of the species, your vet may be able to identify it and determine the treatment needed. Also, bringing the plant helps to evaluate exactly how much and what part of the plant was eaten. A tiny bite of a certain plant leaf may be safe, while the berry or flower of the same plant is lethal.
Holiday plants vary in their toxicity. Lilies (all of the Lilium family and Hemerocalis species), amaryllis bulbs and mistletoe are the most dangerous. If you or anyone in your household suspects that your cat may have ingested any part of a lily, no matter how small, please seek immediate veterinary attention. Hesitation may mean the difference between life and death for your cat! If more than 6 hours pass between lily ingestion and treatment, your cat’s chance of recovery decreases from fairly good to guarded-to-poor, and you can expect some long-term kidney damage.
There are several species of mistletoe including Phoradendum and Viscum – some of which are highly toxic and some of which are less so. Any type of mistletoe ingestion should be brought to the attention of your veterinarian.
Holly (Ilex spp.) – certain species contain the methylzanthine Theobromine (also theophylline which is used as a respiratory aid, and caffeine – you know what that does! J) in all parts, but concentrated in the leaves. Theobromine is the toxic substance that is also found in chocolate. Leaves can cause cuts or irritation in the mouth and esophagus. The berries, which contain glucosidic saponins, are mildly toxic to humans in small quantities, but can cause toxicity to varying degrees in pets. It is best to contact a veterinarian if your pet has ingested holly – more about Holly toxicity.
Jerusalem cherry (Solanum pseudocapsicum) is a decorative species of nightshade with bright red berries that are poisonous.
Poinsettias (Euphorbia) have gotten a bad rap as an extremely poisonous plant due to an urban legend dating back to 1919 – reference for poinsettia myth. They do cause some intestinal upset, but rarely cause death. Pine needles and Christmas cactus usually cause irritation and intestinal upset but are less toxic. The most common signs of plant toxicity are: vomiting, diarrhea, abdominal pain, and excessive salivation (drooling).
If you have a live tree, Christmas tree water may contain fertilizers or preservatives and stagnant tree water can breed bacteria, but ingestion of a small amount of water does not usually cause severe issues. Covering the water with chicken wire or other mesh allows you to refresh your tree, but prevents your cat from drinking the water. Pine sap is not toxic but is sticky and hard to remove. Cats may lick excessively or pull at their fur if sap becomes adhered to their fur. Vegetable oil works better than shampoo when removing sap from your cat’s fur.
Exposure to plants in the Lily family is far and away the most serious holiday threat. I have seen more deaths in cats due to this, than all the other toxic plants combined.
Some non-toxic winter plants that you can safely place in your home include: Christmas palm (Veitchia merrillii), Christmas orchid (Cattleya trianaei), Christmas dagger fern (Polystichym spp), and Mistletoe cactus (Thipsalis cassutha).
Foods
All members of the genus Allium (onion, garlic, leek, chives, shallots, and scallions) can be poisonous to both dogs and cats. Toxicity can cause damage to the red blood cells (RBC), resulting in Heinz body anemia. In particular, cats are 2 to 3 times more susceptible to RBC damage from these components than other species. While specific studies have not been done with garlic as to the safe levels of ingestion, acute onion toxicosis occurs in animals that eat more than 0.5% of their body weight at one time (less than 2 Tbsp. for a 10lb. cat). However, smaller doses given regularly over a period of time will cause the same problem.
Drinks with milk or cream such as alcoholic eggnog are a concern both because most cats are lactose intolerant and because cats are very sensitive to alcohol due to their small size. Even small amounts of alcohol can be fatal.
Chocolate ingestion can be serious, leading to seizures, if a large quantity is ingested. Chocolate toxicity varies by type of chocolate ingested – baker’s chocolate contains a higher concentration of Theobromine than white chocolate. Any ingestion of chocolate should warrant a call to your veterinarian, however. This is usually less of an issue for cats than dogs since they don’t seem to want to eat pure chocolate, but it should still be kept out of reach.
You should refrain from giving bones to your cats. Unlike dogs, cats do not have the instinct to gnaw on bones – and even dogs can damage or prematurely wear down their teeth with too much bone-chewing. Small bones can cause choking or bowel obstructions. Ingestion of broken bones can cause perforations of the intestinal tract, so if you offer turkey meat, make sure it is boneless.
In addition, the herbs and spices that the turkey or chicken is cooked with can be a problem. Sage is an herb that cats are extremely sensitive to, and can cause an upset stomach or depression of the nervous system. Also, as above, onions and other members of that family can cause anemia. If you want to offer your cat turkey, cook up some unseasoned bits on the side, rather than sharing from the family’s bird. It is doubtful that cats can taste the spices the same way humans can, anyway.
Medications
Medications are not something that people think about as a holiday hazard, but during this chaotic time, when many guests may be staying in your home, be vigilant about any medications that may spill, especially as family members that may be coming to stay may bring in medications that aren’t usually in your house. Cats lack some liver enzymes and metabolize many medications poorly; one Tylenol or Ibuprofen can be fatal to a cat. If your cat is on medications for her own health issues, ingesting additional human medications may interact with those she has already taken with devastating results. If you think your cat has ingested someone’s medication, please call a veterinarian right away. Have the pill vial handy while you are on the phone and bring it with you to your appointment so that you can give all the important information to the doctor about what kind of medication it was, the dose and an estimate of how many pills were in the bottle. Make sure that you are also aware of all the medications your cat normally takes and when the most recent dose was given. If your cat has ingested someone else’s medication and is due for a dose of their own medications, DO NOT give the normal medications until you have spoken with your veterinarian.

Excessive Drooling
When cats drool, we should always wonder what is causing this symptom. Although some cats will drool when they are purring excessively and really comfortable, most drooling cats are having a problem that needs our attention. An outdoor access kitty may have some of the most serious culprits to blame such as a broken jaw, or some other head trauma, including battles with other animals. Indoor only cats can avoid these episodes but may still have reason to drool excessively. In many cases the drooling is directly due to pain, so it should be addressed immediately.
Dental disease is the most common reason to drool for indoor only cats. This type of drooling is often associated with a foul odor and sometimes even blood in the drool. These additional findings at home absolutely dictate that the cat be examined immediately. Most cats are not receiving home care (getting their teeth brushed daily!) and most owners do not inspect their cats teeth with any frequency at all. Genetics are the primary factor in a cat’s tendency to develop dental disease and some studies indicate as many as two thirds of cats have dental lesions by age 3. Resorptive lesions of the teeth are the most common type of dental disease in a young cat. In addition to these common resorptive lesions, we also see classic periodontal disease of the mouth where tartar has invaded the gum line and destroyed the periodontal ligament. The difficulty of home care and the reluctance of cats to allow oral inspection dictate that they have an oral exam often; and, that we are proactive with dental prophylactic cleanings to identify and minimize these problems. Drooling will commonly be seen with all forms of dental disease, including infectious stomatitis, peridontal disease and odontoclastic resorptive lesions.
Another cause of drooling in an indoor only cat would include an oral mass. We do see mouth cancer in cats and early treatment is crucial to success. Unfortunately many oral cancers do not leave us with favorable treatment options. These cats often have swelling of their face, and sometimes even a deviation of their normal jaw alignment. If your cat allows, open and close their mouth as you look from the front. The jaws should “go together” nicely and then we know the cat has proper dental occlusion. Sometimes, periodontal disease will cause swelling of the face and poor dental occlusion. A veterinarian can help you differentiate these causes upon oral exam. Any excessive drooling should be seen by the doctor, especially if poor dental occlusion is noted. Mouth cancer is most common in older to middle aged cats, rarely seen before about 7-8 years of age.
Indoor only cats sometimes get bored and I have seen foreign bodies lodged in the oral cavity. I removed a sewing needle that had imbedded in the hard palate of a bored indoor only kitty. I also removed a very stubborn twigg that had lodged in an outdoor access cat’s mouth. Both if these cats had excessive drooling and the drool had begun to smell foul. Fortunately, they both recovered very well. It is worth mentioning that all causes of excessive drooling seen in the indoor only cat can also be seen with outdoor access kitties.
The final cause of drooling to cover is drooling due to nausea. Many cats are nauseous, even though they do not vomit. Some cat doctors even go as far as to say that inappetance or anorexia is the most common sign of nausea. Many of these cats will drool either periodically or consistently. If a cat drools when food is placed in front of them, and they then do not consume the food, nausea should be considered. Causes of nausea are numerous and many cases have multiple causes. As you can see from this blog, a drooling cat should be seen by a veterinarian very soon after the symptom is noted.
