Are Ferns Toxic to Cats? Here’s What You Need To know
Ferns are frequently seen in gardens and houses. Among other things, the fern was known to enjoy lasagna and the fictional cat Garfield. Is this popular houseplant indeed safe for cats to devour, or is it best to keep it out of reach of cats or in a room with closed doors?
According to the ASPCA, cats are not likely to be harmed if they eat a small amount of true ferns. The challenge is pinpointing which plants are “true ferns” and which ones don’t. There are some plants that have the name fern in their name, but they are not true ferns. These plants can sting cats.
Read on to find out which plants are true ferns and which are not, and the symptoms of fern poisoning if your cat ingests a plant which is not a true fern.
Are Ferns Toxic To Cats? What You Need to Know
Ferns are not harmful to cats, but you should make an effort to prevent your cat from eating the entire plant. There are some plants that resemble ferns that can be hazardous even if they don’t truly belong in the fern family.

Is it Safe for Cats to Eat Ferns?
Fortunately, the majority of real ferns are cat-safe. The ASPCA states that the following plants are real ferns and are often safe for cats:
- Cactus fern
- Fern of Boston
- Blade fern
- Deerhorn fern
- Rock fern
- Mother fern
- Fern in maidenhair
- The rabbit’s foot fern
- Bird’s nest fern
The confusion over which plants are truly ferns and which are simply termed “ferns” is the problem in this situation. Some plants with fern-like names or looks, in contrast to real ferns, which are often safe for cats, can actually be toxic to them. The asparagus fern, a plant that is extremely deadly to cats, is the most common example of this.
Although cats aren’t believed to be poisoned by these plants, any plant might have unpleasant side effects if consumed in excessive quantities by cats. For instance, if your cat consumes too much Boston fern, she’ll likely feel sick to her stomach. The majority of the time, though, real fern-related symptoms aren’t severe enough to require medical treatment.

Do Ferns Cause Illness in Cats?
Cats are intelligent animals, but they are also not completely danger-averse. They occasionally come too close to the neighbour’s dog. They occasionally seem to be choosing fights with the larger and more powerful cat from the house behind them.

Which Plants are Dangerous to Cats?
It is advised to avoid a few fairly common houseplants if you have curious cats who like to gnaw on stuff around the house since they are poisonous to cats. The following are a few examples of common dangerous houseplants:
1. Money Plants
The money plant, also known as crassula, is an easy-to-grow succulent. Like with other succulents, you don’t need to worry about watering them too regularly. These are dangerous to your pet animals, including cats, horses and dogs as well.
2. Sago Palm
Sago palms are a typical addition to homes since they may improve the quality of the air within.
3. Snake Plants
Snake plants are perfect for hallways and other indoor locations with limited access to natural light since they flourish in low-light conditions. However, if cats or dogs eat saponins, it might make them throw up and lead to other issues.
4. Peace lilies
During the Easter season, peace lilies are very popular. They have gorgeous white blooms and are regarded as low-maintenance plants. However, they do contain calcium oxalates, which can cause your cat to vomit as well as a number of other health problems.
The benefits to human health are not the only reason why aloe vera is a popular indoor plant. The plant does not have the same benefits as cats, and consuming it might be harmful.

2. Banana Plant
Also known as the weeping fig, the banana plant can be more challenging to grow than other plants due to its huge leaves.
3. The Spider Plant
The spider plant is a houseplant that cats may eat without harm. But if your cat often snips the leaf tips off, the spider plant can start to look ragged and aged.
4. Venus Flytrap
The odd and interesting carnivorous plant is known as the venus flytrap. The most well-known flytrap is the Venus flytrap, which won’t try to eat or damage your cat but will close around and devour insects and spiders.
