Hi, I have 2 beautiful cats, One of them has been ill for some time now and was eventually diagnosed as having an over-active thyroid. Leo is 17 and used to weigh a whopping 8.5kg 2 years ago. He has been on 15mg of Vidalta for over a year now and his weight has dropped again. He now weighs a paltry 3.6kg and the vet has increased the dose of Vidalta to 25mg a day plus a painkiller. Poor little mite cannot use his left leg as it keeps folding under him. (It is horrendous to watch him trying to move around - but he does not seem in pain.) Vet said he has so little muscle that at moment the leg cannot support him. I'm on a mission to feed him up but have to watch what he eats. Give him food too rich and it emerges from one end or the other! Not pleasant. I have changed his food to Hills Science Diet (dry) and yesterday started cooking him chicken breast. I boiled them in water and fed him some every hour. In total he ate 2.5 - his brother Max had a small amount. Does anyone know of any kind of food I might be able to feed him that would help slab some weight on. I would like to say money is not an issue but unfortunately it is. However, after last Friday's vet bill the remainder of my wage went on the cats. (I'm managing on cheap bread and beans for the time being.) Any suggestions would be gratefully received and hopefully I can pull him through this. He is a tough little guy and I miss him diving around like a loonatic.
