My older cat (12-ish) is finding it a bit harder to get upstairs these days - seems to be dragging one leg slightly. She's absolutely fine on the flat, can get up onto my bed ok and still nips in and out of the catflap. I'm reluctant to take her to the vet as she gets scared and extremely aggressive so I'm not quite sure how they'd even examine her. I thought it might be arthritis so have tried a food supplement (Easeflex for cats) but she kept avoiding the bits of wet catfood that it was in, and also a cat treat for stiff joints, but she wouldn't take them. Has anyone found a solution in a similar situation?
