Adult cats can eat pothos leaves. Adult cats have better gastrointestinal function and can digest an appropriate amount of pothos leaves. Kittens should avoid eating green radish leaves because their gastrointestinal function is weak, and green radish leaves can cause physical discomfort, allergies or poisoning. If you have growing kittens at home, it is recommended that the owner place the pothos in a high place, out of reach of the kittens.
