Protect Your Cat From Poisonous Plants

If you have a new kitten, chances are you’re watching her buzz around the house, checking out anything and everything! Your home is an exciting new world for a curious kitten but there are some dangers you need to watch out for. One area of concern has to do with houseplants. Even some adult cats can get into the habit of munching on forbidden greenery. Although it may seem innocent enough, most plants are poisonous to cats. The effects can range of minor irritation to being absolutely deadly. If you have hanging plants it creates even more enticement as the kitten or cat bats the plant in play and then bites down. Some cats who don’t have enough environmental enrichment can get into the habit of playing with and nibbling on houseplants just out of boredom.

What Plants are Poisonous?

For a list of poisonous plants, visit the ASPCA website. The list contains many pictures as well for easier identification. According to the ASPCA, here’s their list of the 17 most poisonous plants:

  • Lilies
  • Marijuana
  • Sago Palm
  • Tulip/Narcissus Bulb
  • Azalea/Rhododenron
  • Oleander
  • Castor Bean
  • Cyclamen
  • Kalanchoe
  • Yew
  • Amaryllis
  • Autumn Crocus
  • Chrysanthemum
  • English Ivy
  • Peace Ivy
  • Pothos
  • Schefflera

There are some common plants, such as the dieffenbachia, that can cause intense burning and swelling of the tongue after just a few small bites. This can lead to difficulty in breathing. I see these plants included in many gift arrangements. In fact, several gift arrangements containing the highly toxic plant were sent to our house by well-wishers when my television show premiered. We ended up taking all the plants to the local nursing home.black cat hiding partially in long grass.

It’s important to make sure all potentially dangerous plants are kept completely out of reach. Some plants can cause immediate death no matter how quickly you get help so know the plants you have and remove the ones that are deadly. If you are going to keep plants, either indoors or outdoors, at the very least, make sure you know the names of them in case immediate identification is needed during a crisis and do your best to keep them out of your cat’s reach. When it comes to an outdoor cat, it’s pretty difficult to protect her should she decide to chew on outside greenery.

Signs of Plant Poisoning

Many of the signs will depend on the type of plant ingested. Some signs may include:

 

Excessive salivation

Vomiting

Difficulty in breathing

Diarrhea

Fever

Abdominal pain

Mouth and throat ulcers

Trembling

Irregular heartbeat

Red, itchy skin around the mouth

 

Treatment for Plant Poisoning

The treatment will depend on the type of plant ingested. If you can’t identify the plant, take it or a piece of it to the veterinary emergency clinic with you because they may be able to identify it. Your veterinarian isn’t necessarily a plant and garden expert but you stand a much better chance of helping your cat if you bring the plant with you so they can attempt identification.

If you think your cat has chewed on a poisonous plant, contact your veterinarian immediately. If it’s after hours and there isn’t an animal emergency clinic in your area, call the ASPCA Poison Control Hotline.veterinarian examining cat

At the veterinary clinic, your veterinarian may induce vomiting in the cat, depending on the type of plant. Activated charcoal may also be given to absorb the poison. Additional tests may be administered to determine the extent of any organ damage. Your cat may also be put on fluid therapy.

If you’re unable to get to the veterinarian or emergency clinic, depending upon the type of poison, you may be instructed to induce vomiting. Don’t do it on your own unless you’re instructed to because in some cases, vomiting will cause burning and irritation again – as would be the case with the dieffenbachia plant. In some cases you may be instructed to use milk to coat and soothe the intestines. Again, don’t attempt anything until you’ve been instructed on the best course of action by a veterinarian.

Keeping Your Cat Safe

In our house, we’ve decided that it’s not worth the risk so we don’t keep live plants indoors. If you decide to keep plants or have chosen to only keep the ones that aren’t deadly, make sure you coat them with a bitter anti-chew spray. You can find these sprays, made especially for plants, at your local pet products store. Spray the plants, including the undersides of the leaves, being careful not to get any on your hands. I recommend wearing disposable gloves because the spray REALLY tastes awful. If you spray the plant indoors, protect your floors and carpets by putting newspaper down around the plant first. In some cases you may have to do a repeat spray in a couple of weeks.kitten on a blanket

Keep hanging plants cut short to reduce temptation. When it comes to plants near windows, keep in mind that cats tend to love sunning themselves at the window and also watching the birds outside. To reduce temptation, make sure your cat has several safe, plant-free window-lounging locations. Put a window perch at your cat’s favorite window or locate a cat tree nearby.

Redirect your cat’s interest to more interesting things. If the plant nibbling is happening out of boredom, step up the environmental enrichment. Here are some examples:

 

Conduct interactive play therapy sessions at least once a day

Incorporate the use of food-dispensing toys

Rotate toys to keep them interesting

Put out some boxes or open paper bags with toys inside

Get a sturdy cat tree and place it by a window

Keep a lid on the stress level in the home

Provide safe chewing options (such as cat dental chew products)

 

Growing Safe Greenery for Your Cat’s Nibbling Pleasure

If you have a hardcore plant nibbler, try growing some safe kitty greens. You can buy these kits at your local pet product stores. You can also buy a patch of rye, wheat or oat grass at your local organic food store or you can grow your own from seeds. Don’t use grass from the lawn because of the chemical fertilizers, weed killers and pesticides it may contain.
