I will be going to the vets in a while with 2 cats, 1 14 yrs and one 16, and I am not too sure I will be bringing 16 year old Gypsy back with me, she has always been small and weighs less than 2 kg, she came when she was a few weeks old from one of those houses like you see on TV occasionally, loads of cats and you have to wipe you feet when you come out. Her bowel problem which she has had for a long time is worse now. Also 14 year old Teddy had had a huge fit, although now she seems fine I would rather air on the side of caution and take her for a MOT.
