House/Garden Plants and Foods Poisonous to Cats
Actual reports of animals getting seriously ill from eating plants are relatively infrequent, compared to reports of poisonings from household products or drugs.
Although many people believe poinsettias, ivy and mistletoe are dangerous plants, and while these plants do have toxic potential, they seldom cause serious clinical signs if eaten.
Much of the motivation for chewing on plants involves boredom and other psychological factors, such as recent changes in household (moving, moving furniture, demise of a loved one, etc.), so it may be worth noting if your kitty begins suddenly eating houseplants he/she used to ignore, and discuss with your Vet. You might want to consider planting lawn grass in a pot for them - it is not harmful.
Covering soil of houseplants with aluminum foil will discourage digging in dirt and decrease the likelihood of cats eating your plants.
Plants known to be toxic should be kept away from your kitty. Please refer to the links below to select safe houseplants.

In short:
- Keep all harmful substances mindfully and safely stored far away from Kitty's reach.
- Keep track of baits and properly dispose of them when they have expired
or are not needed any longer. Record the date baits were put out and name of bait.
- Maintain all information possible on harmful substances - in case of emergency this information will be CRITICAL for diagnosing possible poisonings, as well as treatment. If Possible, bring container. It is the actual active toxic ingredient contained in the substance that will determine the level of danger present. Different ingredients require different treatments, so this information is VITAL.
In Case of Emergency
If poisoning is suspected - call your Vet and advise them that you will be coming in ASAP. Bring containers of substance to your Vet.
Helpful Suggestions
Wrap kitty in towel to avoid hurting you or itself, and to prevent further ingestion if source of poison is on the coat itself.
Do not administer home remedies to induce vomiting.
Know your Vet's emergency situation procedures, (especially after hours).
Keep telephone numbers handy for:
- Your Vet
