Hi all, Really thank you all for answering so fast. It's over again for the moment and I hope it indeed was just a hairball. The other cat loses much more hair, so I find it a bit odd that it's she who has this problem.But if she has it again soon, I 'll call the vet to ask if there's anything else I can do. This particulr cat is a bit weird, she keeps spinning, so I never know if she likes something or if she doesn't. Anyway, THANK YOU ALL!! Sorry for sending this to the GML. Sarah
