Thanks everyone
It's the wet Royal canin sensitivity that I was given and he refused to eat. When I went to work last night he was a little bit improved and was accepting a gentle cuddle and had a nibble of chicken but when I got home this morning he hadn't eaten the fresh chicken and RC I put down for him and was the same as yesterday morning - completely un-responsive under the bed and he'd been sick on the duvet again
Just been to the vets and they've kept him in, he's going to have IV fluids and injectable Zantac. I can ring at 16:00 to see how he is and they said I could visit after that.
She spent ages feeling his kidneys and I had a horrible sick feeling come over me, it reminded me of Andrea's Leo
After about 10 mins of squeezing/poking she said that one kidney felt slightly bigger than the other but that they quite often are and that she couldn't feel any nodules etc so wasn't concerned about the size difference.
btw - he seems quite nauseous. The vet gave him a jab last week and said there was a tablet version that isn't licensed for cats but he thought the pill was too small to cut into quarters. I really want to give it a try - It sounds like it must have been the generic version of Zantac?
PS - Just checked and Zantax is ranatidine. I have some Sainsbury's generic ones - do you know what the cat dose is? - I could try to give it to Clapton and avoid a 10-mile round trip to pick it up from the vet.
The vet said the same to me, the injectable form is licensed but the liquid/tablet form isn't. They only had 150mg tabs which are too big a dose to split. She said the dose was about 10 to 11mg so around a sixth of a Zantac 75 (Ranitidine 75) tablet but best to check with your vet as I think Riley weighs more than Clapton so prob needs a bigger dose
