My kitten Harley (1yr old) twitches when she is resting. I know cats twitch in their sleep and this is not what that is. She only does it when she is on her side or on her back. It's more like shivering than anything. We're planning a vet appointment next week and she is way too much of a scared cat to feel comfortable at the vets, so I may just get a video of her doing it.
Any ideas what it could be?
