Thanks Gill, I am going to sleep on it overnight, but my instinct is to cancel it.
He is only 9 and a half years old, but is much older than his years due to everything he's been through.
He had a laminectomy at the age of 6 and is slighty disabled as a result: he often falls over when chasing the girls
After recovering from that, he developed diabetes and his original owners couldn't cope and signed him over to the CP - that's when I fostered him, and ended taking him on permanently when I was told he was not rehomeable (two injections a day and peeing in the house).
His diabetes has been practically impossible to regulate and in January, blood tests indicated that this is almost certainly due to a condition called acromegaly (a tumour on the pituitary gland responsible for the growth hormone). We were offered a free CT scan to confirm the diagnosis by the RCVS - who are doing research into this, but declined the offer becasue we thought he had been through enough, and there was no way I was going to put him through radiotherapy treatment with little guarantee of success and a lot of risk.
He also has arthritis in his back legs, and a large polyp in his right ear; he really hasn't had the best of luck.
Now you can see why I was so reluctant to have him vaccinated and was surprised the vet agreed too.
I have had a quick word with someone at the practice, but they just said his symptoms were probably a coincidence and down to something else and that I should go ahead with it. I don't know, the last time I had a cat sneezing, I was told (by a different practice) that this was probably due to an allergy/dust in my house. Two days later, the kitten - who had just finished her course of injections, developed full blown cat flu.
I wanted to get him done just in case I had an emergency foster in the house sometime, and although my cats only have access to my garden, I know flu/enteritis can be bought in on shoes/clothes etc.
Life is never easy is it...
