Houseplants can be a great addition to any home, providing a touch of greenery and life to any living space. While they can be beautiful and beneficial to us humans, many plants are toxic to cats, and can even be fatal if ingested. It is important to be aware of which plants can be dangerous to cats so that you can keep your furry friends safe.

First of all, it is important to note that cats are very curious creatures, and quite likely to explore your houseplants if given the chance. Some cats may even enjoy chewing on leaves or stems, so it is important to always be aware of which plants can be dangerous.
