Hi, My cat started meowing like he was in pain and started backing up quickly as if something was hurting him. It only lasted a couple of seconds and afterwards everything seemed fine, he ate, he played, but 30/40 min later he did the same thing again for only a few second and everything was fine again. I can’t find any spot that’s painful to touch. Later he was curled up napping, he turned his head, meowed painfully again, and then continued to sleep. He pees and poops normally.
