In their natural environment, cats would have access to a variety of plants to play with and chew on. So don’t be surprised when your indoor cat chooses your houseplants as a way to calm those instincts.

String of Hearts Plants Can Cause Digestive Issues

In general, even non-toxic houseplants can cause stomach upset, lack of appetite, vomiting, and may even lead to diarrhea in animals who ingest a large amount of the plant material.

This is true of most animals but can cause even more problems for cat owners because felines are very agile and can jump very high, often gaining access to a plant that’s placed high up out of reach.

But, if your cat does eat a large amount of plant material from a string of hearts plant and is suffering any adverse side effects afterward, you should consult with your veterinarian for advice on what to do.

Cats Could Get Tangled in the Vines

One of the most recognizable characteristics of the string of hearts plant is its long vines. These vines can grow quite long and may provide a temptation for curious cats who like to swat at things. This could cause your frisky pet to get tangled in the vines, causing potential damage to both the plant and your pet.

If you have a particularly curious cat in your home, it may be necessary to keep your string of hearts plant somewhere out of reach. Since they do very well in hanging baskets, you could try suspending the plant from the ceiling so the cat can’t reach it.

House Plants Present a Choking Hazard

If you have a cat who is very interested in eating your string of hearts plant the stem, leaves, or vines could become a choking hazard. Cats usually don’t know what’s best for them and may try to eat and swallow parts of the plant. This could be a risk for the cat if anything gets lodged in its throat and causes an obstruction.

For the most part, the plant material will be soft enough to pass through a cat’s system without getting stuck. But, if your cat is having trouble breathing for any reason, seek emergency veterinary care immediately.
