My bunny is leaving wet spots on pillows that he lays on for a long time, but it has no odor so it cannot be pee. I was wondering if anyone might know what this is or what it could mean?

Thanks!

Could he be drooling?

I'm thinking the same as LPT.

Bandit also leaves wet spots when on my bed too..he likes to lick the sheets for whatever reason..watch him maybe he's doing the same thing
