Are Peanuts Safe For Cats?

Peanuts are not toxic to cats, unlike onions or garlic. So from this point of view, yes they are safe for cats in the short run but as with all foods, too much peanuts might harm your little feline friend in the long run because peanuts contain high amounts of fat which can not be properly digested by cats.

Another safety concern can be the shells which can be a choking hazard. Peanut shells can be easily crunched by cats but this does not mean they can easily swallow them. In addition to being a choking hazard, peanut shells car hard to digest and can become shard-like objects in cats stomachs and can even cause small bleedings which can be very painful for your feline friend.

Another health hazard for cats is salt. A lot of commercially available peanuts contain salt, sugar, spices, additives and flavors such as chocolate. Always remember that these are not good for your cat. Chocolate is even highly toxic and can cause serious health issues and even death if consumed in high amounts.

If you decide to give your little furball peanuts, make sure that it is raw, unsalted, unflavored and without any additives.
