DittoI give mine pureed pumpkin. When it is in season I buy lots and cook it. When I run out I buy canned pure pumpkin.
The kitten gets two teaspoons a day and MowMow gets a tablespoon a day.
The extra fiber helps them pass hairballs. I notice if I stop for more than a few days MowMow starts to cough up hair.
Milky is the same. He doesn't throw up hairballs or anything. I give him a malt flavoured Laxatone for hairballs, just a pea size once or twice a week mixed into his food. Then I grow wheatgerm every other month and give him a small bunch to toss and eat and play with.I grow grass from oat or wheat grass seeds from a health food shop. But mine don't get hairballs or throw up, they just like to eat grass
