It's super cold where I am and my cat loves this fluffy red blanket. He sleeps on it all the time and we like to tuck him in with it since it's chilly. Sometimes I like to be silly and put my hand under his body since he's warm and soft but when I did, i realized it was wet. He sat up and there was a wet spot on my blanket that smelled like poop. My hand was also wet and smelled like poop. He hasn't had any behavioral changes and this is the only time it's happened. He doesn't act like he's in pain and he's running around being silly like always. Should I be concerned??? Is this a normal thing that just happens sometimes or should i go to the emergency vet?
