Unique Non-Toxic House Plants Safe for Kids, Cats, and Dogs

2. Boston ferns are the only safe fern

Ferns are a popular house plant, but many people don't know they are extremely toxic. The only kind of fern that isn't is the Boston fern. So, if you are looking for a pretty plant that your cat can also gnaw on, they are the way to go. They are also fairly low maintenance. The plant will do best in an even-parts mixture of peat moss, sand, and garden soil.

It is also important that the pot you are using is large enough to allow the fern to sit comfortably without its roots being near the drain holes. The fern can be planted about halfway to the top of the pot, leaving one inch of space at the top. Ferns do well in warmer, more humid climates —between 65 and 75 degrees. Keep the soil moist and out of direct sunlight to maintain the plant's health.
