Cats can eat small amounts of string cheese, but
Cheese strings are high in fat and lactose. This milk product can be difficult for cats to digest. Some felines are also lactose intolerant. This means that they can’t react to lactose properly, which can lead to digestive problems such as diarrhea or upset stomach.
If you decide to give your cat a small cheese string as an occasional treat, watch for adverse reactions. Remember that cats have special nutritional needs. Their main diet should be a balanced cat food. For further advice on the best diet for your feline, please consult your vet.
