why sometime my cat eat grass?

Cats sometimes get upset stomach, they need to throw up. that's why they eat grass. but it doesn't eat any grass... though. it will only eat straight grass (don't know what it's called).

This is normal, also sometimes cats do this to remove hairball too. (cats can't spit)

Cat's eat grass if they want to be sick...the grass helps them to be sick.

they do that because they have an upset stomach.

i dunno because our dogs also eat grass

Maybe it thinks it's a cow. :)

ALL CAT DO THAT , BECAUSE ALL ANIMAL NEED FIBER

Usually a cat or dog does this when it has an upset stomach

I think your cat got diarrhea.

animals like the taste of grass, you can buy grass at the pet store that wont make them vomit.

Are you sure it is a cat it could be a cow

doesn't that make them vomit so then they won't have a tummy-ache

Basically for the same reasons why dogs eat grass. Which is basically the same reason why you would take pills that would stop you from puking and stuff.

well when my dog does that , the vet says he has a stomach disorder. A deworming injection will stop it

its ok. my dog does the same too.. Animals have natural instincts to seek out these sorta natural herbal treatment plants; especially when they are feeling a little bit whoozy. :)

ur cat is unwell. grass acts just like esapgol, the husk many people eat as a purgative. but grass acts as a purgative for cats only. u dont try that out!

Because the cat is nauseous. They do that to settle their stomachs.

She could have an upset stomach. Animals like dogs and cats naturally do that.
