I can't recall ever noticing this before till today. My cat was laying on the couch and suddenly there are twitches near her midsection. Only lasts a few seconds but then comes back again. I've had Marzi for close to 13 years now and have never seen this. She goes to the vet for a routine wellness checkup and so I'll mention this. She also shakes her head frequently and seems to be bothered by her left ear. This has happened before and after the vet cleaned her ears a few months ago the issue settled down. Thanks for any suggestions on the twitching. She is not on any flea medications, etc. Except for these occasional twitches, she behaves and eats normally.
