VALENTINE’S DAY IS coming soon, so if you are making your plans to give flowers or decorate with flowers be aware of some flowers very commonly included in cut bouquets and arrangements, even from the grocery store, that are mildly to highly toxic to cats, and many to dogs as well.
. . . . . . .
Above, Lucy anticipates a taste of flowers I’d received after my first poetry reading which was right before Valentine’s Day in 2007. The bouquet includes red roses, white carnations and ferns. The roses are fine, and this type of common fern used by florists is fine as well, so they are safe if she wants to snack on them. The carnations can cause only mild tummy upset if they eat too much, in the same category as poinsettias, so I permit those. Now, the festive Hershey Kisses in the milk glass dish are another matter entirely, and even though most of my cats just played a little hockey with those I got a covered dish for colorful candies.
Many of the cautions in this article apply to dogs as well, but cats are a little more sensitive to certain plants—lilies, for instance, may give a dog a tummy ache but they may kill a kitty—plus kitties can jump and climb and get themselves into truly amazing places, so I am focusing on cats for this article. But for any pet, please be cautious of flowers and plants and keep the list of toxic species linked at the end handy.
Cats aren’t necessarily particular in what greens they’ll nibble on; generally they’ll try anything green and fresh, and some cats will completely chew down a plant that can’t have tasted very good and wasn’t very easy to chew. They don’t stop with leaves, either, but will eat the petals off of a flower.
And while many pet owners know the dangers of various houseplants, most people don’t associate cut flowers with these dangers, yet many cut bouquets include flowers from some of the most toxic plants for cats and dogs. What makes it complicated is that we recognize them when they are individual growing plants, but may not even notice them in a mixed bouquet.
Some plants cause gastric upset which can be a mess to clean up and is uncomfortable for your cat, but it can also have long-lasting effects such as ulcers in the mouth or digestive tract, and excessive vomiting or diarrhea can dehydrate and even kill a very young or old cat.
Other plants more seriously affect a cat’s organs and can be deadly within hours, even to a healthy cat.
Lilies in all their forms
Lilies in just about all their species can cause kidney damage in cats which is permanent and can lead to kidney failure within 48 hours if left untreated.
Sure, we know the big white lilies at Easter, but consider an everyday small grocery story bouquet: a few yellow mums, some white daisies, pink carnations, fern, baby’s breath and—alstromeria, a South American lily, which comes in colors from white to scarlet.
Or a medium-sized get-well bouquet: Yellow roses, white mums, blue larkspur and—two big pink Stargazer lilies.
And what used to be part of my favorite backyard bouquets in spring: pink climbing rose, red rambler rose, Shasta daisies, blue widow’s tears and—big orange daylilies, as well as any of the other domestic or hybrid lilies that you may grow in your back yard.
Instead of a bouquet of cut flowers we’ll often give or receive bulbs forced to bloom early in baskets and pots. I used to welcome the new year and the last long days of winter with forced bulbs all over my house as pots of paperwhite narcissus, trays of daffodils and baskets of mixed fragrant tulips, hyacinth and crocus along with squills and starflowers.
Then I learned that any part of these plants can not only cause gastric upset but also organ damage, specifically kidney damage and heart failure. I remembered a healthy fifteen-year-old cat I’d lost years before to acute kidney failure—her kidneys just failed one day and I had to put her to sleep the next. This can happen without an outside stimulus, but I’ll always wonder if that was the cause and I have never forced bulbs in any place my cats could get them since then.
In the same way, onion and garlic, also bulb-forming plants though they are considered food, are toxic to cats.
While most plants are not that immediately toxic, other plants, such as azalea and rhododendron, lily of the valley, ivy and yew can be deadly to cats in impaired health or kittens, since they’re small enough to get a big dose with an enthusiastic bite. Though not deadly for adult cats in good health, they’ll often cause extreme abdominal pain, nausea, salivation and vomiting. Repeated exposure can be cumulative with some plants.
Sometimes cats have no sense
“Oh, she’ll stop eating if she gets sick,” or “she won’t eat this, it’s got little thorns”, don’t believe that. I’ve seen cats try to eat cacti, drool while they are chewing aloe and vomit up philodendron and go back to eating again. Don’t rely on their non-existent common sense, just remove the plant.
You can’t really punish them for following both a natural impulse and a physical need. We don’t really know why cats, obligate carnivores with no obvious need for greens, chew on grass, but some guess they help cleanse their mouth and digestive system, and to add fiber to their primarily protein diet to aid in elimination. An indoor kitty will take what she can get to simulate the natural outdoor environment she craves.
The problem is that, while you may get some cats to stay away from your plants, most cats will return again and again, even if they suffer discomfort from their snack. The best way to keep your cats safe from plants is to put the plants completely out of reach—bearing in mind that cats can jump six times their height and can be ingenious about launching from strategic furniture to get into a hanging basket. Sometimes it is necessary to completely remove the plant from the house, no matter how much you like it.
Signs of plant poisoning may include vomiting, diarrhea, and swelling or pain inside the cat’s mouth. If you know or suspect which plant your cat has eaten, identify the plant by name when you call your veterinarian. Bring samples of the plant’s leaves or flowers when you take your cat to the veterinarian for treatment.
Keeping your cat out of your plants…?
What happened to that nice spider plant you used to have? Oops—while enjoying the scene out the window, Fluffy forgot it wasn’t just a clump of grass and chewed it down to little nubbins. Then, because it really wasn’t grass and really wasn’t digestible by her little system, she deposited it back on your carpet in a most inelegant manner.
And that wandering jew? She used it for a bed? I’ll bet she looked sweet.
A determined cat will do what she wants. Remember, you have to sleep some time.
As for the non-toxic flora, even though Fluffy won’t suffer if she chews on it (unless you get your hands on her), you still don’t want her shredding your greenery. Several commercial sprays will give the plant a bad smell and/or taste without damaging the plant with recommended use, and a nibble by Fluffy will not harm her. One product is “Bitter Apple for Plants”, a stronger version of which is available for dogs learning not to chew on everything. Other products are named “Off for Cats” and such like, and simply smell bad.
You can also try your own home brew by dabbing hot sauce on the tips of some of the leaves, or rubbing a citrus peel on the leaf. For the sake of your plants, however, just try it on one or two leaves to make sure you won’t fry the whole plant in an effort to keep Fluffy from eating it.
You could also place “Sticky Paws” on the countertop around the arrangement or plant so that when she steps close to the plant she steps on the product and backs off; please read the instructions on the Sticky Paws package for what surfaces are appropriate for its use.
One other thing to help the situation—and it’s a nice thing to do for your cat even if you don’t have a plant problem—is to plant her own pot of greens and make it available to her at all times. Don’t use regular plant seeds such as grass seed because some seeds are treated with chemicals, at least check before you use them; instead, purchase “cat greens”, usually a mixture of wheat, oats and barley grains, all three of which are not only a pleasure for your cat, but full of nutrition. Some other commercial “cat greens” mixtures contain catnip, a sure winner, sage, parsley, chickweed, colt’s foot grass, and other herbs and wild plants that your cat would eat if outdoors.
Most of these plants can be grown in a small container on a windowsill, and if you keep two containers growing, one available to the cat and one just sprouting, you can have a constant treat for her. These plants need a good bit of sunlight to thrive, so try to find a sunny spot that your cat can get to. It will serve two purposes: because she tends to chew when she’s gazing at the outdoors, you’ve provided exactly what she needs for her little interlude.
I have another article in this series on just this subject entitled “Living Green With Pets: A Garden for Your Cats”.
Keep toxic plant and flower information handy
Your local veterinarians and shelters often have lists of toxic flora has handouts, and plenty of resources exist on the internet.
And as far as those flowers, you just can’t go wrong with roses!
