Hi everyone i just wanted to let you know about what happened to Jet a couple of years ago and wondered whether anyone elses cat had gone though anything similar and what they were diagnosed with.
Jet is a really friendly cat but he suddenly became aggressive, hissing, swiping, etc and when he stood up to stretch and arched him back he would cry out in pain, it was heart breaking to hear. Took him to my vet who did all they could, blood tests, x-rays, etc and couldn't find anything wrong so referred him to another vet. This vet injected something into his back to show up his spinal cord on the x-ray and there was nothing of note on there. He was tested for Fel Leuk, aids, etc and all came back negative but he was still in pain.
He was then referred to a specialist (one of the best in the country) for an expensive MRI scan. This again showed nothing wrong but the consultant could clearly see he was in pain. He subscribed some medication which they use in cats with epilepsy, he had that for 6 months and hey presto no pain and my old cat was back. The whole treatment cost just over £2500 thank heavens for insurance, and in the end the thing that cured him only cost £3.69 for a bottle!!
They've still not been able to say exactly what was wrong, they think it was something psychological!!
