Why do my kittens love tall grass so much?

Playing in the grass mimics hunting so they enjoy it.

And yes, eating regular grass can make them vomit because the edges of the grass are and irratate the digestive tract. It’s best to offer your kitty oat, rye or wheat grass, that you have grown in a pot without chemicals, if they enjoy munching on greens. The edges of those grasses are not serated and won’t make your kitty vomit.

they are just playing you don’t need to worry about them.it teaches them to catch their prey too. eating grass doesn’t makes them sick.
i have read somewhere that if an animals has eaten something wrong then it eats grass to take out that wrong substance.

When cats leap on tall grass, it moves,Right?
And when things move,cats think it is prey.
And when cats eat grass it does not make the sick it makes them well.

cats like to play this teaches them to catch their pray. so don’t worry about them. and eating doesn’t makes them sick. i have heard this from the vet

Cats play with grass because it moves,like prey.And eating it won’t make them sick,it’s actually good for them.

yes grass can make them vomit but they do love playing in it its like cat nip but cat nip is better for them and it gives them a energy boost

cats eat grass 2 help hairballs 2 be upchucked

by playing with grass cats learn to catch their pray it is alos a type of a play for them
also it helps them for digestion as kat and khushi have said

so that they can learn to catch prey also it helps for the digestion
