Hello! My cat recently over the past few weeks has been shivering, to the point where sometimes I think something may be wrong but she acts perfectly fine..so I'm stumped why she might be doing it. She does it mainly when she stretches out before she falls asleep. She will be purring at the same time, I've seen her do it before too right before she gets fed when she seems super excited. I wish I could somehow post a video but I'm not sure how, its only her legs that shake, has anyone else's kitty done this before? I would think if she was in some kind of pain from something it would be more often, but its only when she seems relaxed and happy
