We've thought hard about it & it was okay when it first came in, it jumped up onto the utility workside & woofed down 1.2 sachet of food.
It's only since yesterday afternoon it's gone all mardy, it nearly fell off the back of the sofa when it fell asleep catching the heat from the radiator. We're wondering if it twisted & hurt itself, it's clearly in pain on it's back somewhere just before it's hind legs. It's had a few treats & is now just curled up looking sorry for itself, it's fur is sticking out roughly where we think the injury maybe, but as with cats there's no way to examine. I can see this ending up with a call to the vet tomorrow.
