Food poisoning caused by domestic cleaning products are rare, for the cat is a wary eater; however, beware of indoor plants, as many of them are irritant or toxic.
Some toys can be dangerous for the cats too: toy bells, strings, etc... If you are knitting, beware not to leave the string in a needle.
Cats tend to taste their food before indulging it, so poisoning is fairly uncommon. However, some poisons have a taste that the cat likes, or a cat may eat a small prey that has consumed toxic products.
Cats lack detoxification mechanisms and are less likely than dogs to regurgitate disagreeable substances. A cat's nervous system is very easily disrupted by a number of poisons.
