Both dogs and cats eat grass as some sort of digestive cleansing. They throw it up again quite soon.
Kim, you are very bad!
From experience, only about half of cats do the grass thing.
There's a cat comes to visit our garden sometimes. We call him/her "Friendly Cat". The other day (s)he appeared to be munching on some tall blades of grass.Is this usual for cats? I thought they are carnivores.
Grass for indoor cats is available to buy.
