Need some advice to see if I am being overly paranoid. Our 5 month old kitten has a little cold so we did the steam therapy for like 5 min in a closed bathroom with us in it and a hot shower running. Or kitten started to pant so we immediately brought him back into a normal room and he stopped panting but I noticed his tongue was redder than normal. The tongue went back to normal pink after a few minutes and he acted totally normal and drank and ate and played. Everything I look up about the red tongue is saying bring to vet but its 11 pm and dont want to stress him by going to emergency vet. He acts fine should I be worried???
