Yes you should certainly allow it. It's important for them to have access to it - flat dwellers can even buy a good variety growing inpots for cats to chew on to discourage them from nibbling houseplants, which they only normally do if they have no access to grass. They use it as an emetic to help rid themselves of hairball or other problems.

That's very helpful Stera. I had no idea it was so important for them. He can eat all the grass he wants then. I appreciate your input.

I know when our cat eats grass he'll be sick soon after!
So keep an eye on them and be ready.

Do you put anything on the grass Carenature? Pesticide? Fertilizer? Herbicide?

Our two regularly eat grass and then regurgitate along with whatever was causing the problem, not fur balls in their case as they are Siamese.

That'a amazing Mg. They know instinctively what they need to do.

The cat we have at present is the first one to have trouble with fur ball (even though she is brushed nearly every day) as all previous ones were shorthairs. They still ate grass though, with the predictable result...

Re chemicals, if these are applied only on the short lawn grass there should be no problem as long as there is some longer grass elsewhere, as they will always seem to choose the longer grass in preference.

That's true, he is selective and prefers the longer grass.

Bella chews my Spider plants and I also keep some pots of Cyperus (Umbrella Grass) dotted about the house for her to chew in the winter when there isn't much grass growing in the garden.

Costello is in good company and he sends xx to Bella.

Thanks for commenting everybody!

All three of our border collies have eaten grass and I've always assumed that it aids digestion although they don't cough up hairballs like cats do. Just a point of interest.

I didn't realize that dogs also eat grass. That is interesting - and it's all instinct. I remember my dog 'Skipper' growing up. I took him to the vet for 2 big growths on either side of his head I thought were tumors - they were the size of baseballs. I was mortified when to vet snipped them off and sent us home. They turned out to be 2 big hairballs.

Our cat gets them and they are so difficult to deal with - she hates the brush going over them so we have to know where they all are, and she won't let us cut them off - we could restrain her but don't want to frighten her. Eventually they fall off by themselves as she moults.
