I haven't noticed this before. Are they just his nipples or something? Did he scratch himself while kicking his legs? Flea bites?
He doesn't seem to be in pain when I touch them but he doesn't like it.
Oh ok, thank you! Very reassuring, he's just been going outside for the past week or so and I was a bit concerned, but if it's just a little bite then that's fineThats 100% his/ her belly button (so where their umbilical cord attached), it's looks like that on most cats. It has got a little spot or bite on it that's all. Probably where there is no hair (that's normal) to protect it in long grasses etc. Unless it gets angry or weepy don't worry about it, it will go away on its own in a few days.
