Hi There, My cat was exactly the same from the minute I had her, and she is now 10 months old and she continues to have the odd episode of it still. Initially I kept taking her to the vets who said it was worms-even though she has always been treated regularly. When she was younger the vet advised giving her scrambled egg (without milk), and that always seemed to help and she loved it-she would never eat chicken! Nowadays if she gets it it never seems to affect her in any other way so I continue to feed her her regular food. I have been told it is something she may always have and as long as she is well in herself then I shouldn't worry about it.x
