[jelly baby]

One of our cats is also 20 yrs. She lost a lot of weight and her fur became quite thin over the last 3 months, we took her to the vet and after a few blood tests she put her on thyroid & heart pills, she is slowly regaining a bit of weight, her fur has thickened and she is a little perkier in herself too. The vet told us that thyroid problems are very common in older cats. The tests cost around £50 and the pills cost around £100 a month, quite expensive, but she's worth it, she's been with us since she was 6 weeks old. Good luck with your cat.
