20. Eating Grass
Although cats are carnivores, they sometimes nibble on grass or plants. This behavior may aid digestion or help them expel hairballs by inducing vomiting. Grass contains certain nutrients that may be beneficial to their diet, despite their primary need for protein.
Owners should ensure that any plants their cats access are non-toxic. Providing safe, cat-friendly grass varieties can cater to this instinct while keeping them healthy and happy.
