He's at least 13, possibly a little older. He's started weeing in odd places, become increasingly vocal, he's lost a tooth, his hair is thin in places, he's lost weight, and is just generally not himself. We're at the vet tomorrow, and I guess I'm really just after some understanding and moral support . DH and I rescued him when we first moved in together 12 and a bit years ago along with his brother. Sadly his brother left us 6 years ago. He's just part of us and I'm not ready for him to be failing.
