This can occur if you leave your rat to play in an un-rat-proofed room! Your rat might receive burns to the mouth and paws, loss of consciousness and possibly even cardiac arrest!
What do I do?
Check for breathing. If its not breathing, then you can attempt resuscitation. Be aware that it might not always be effective, your chance growing slimmer the longer the rat has been unconscious. Place your mouth over the rat’s nose, and breathe gently about 30 times a minute. At the same time, use your thumb and forefinger to gently compress the chest directly behind the elbow about 60 to 100 times a minute.
If your rat is breathing, or you successfully revive it, keep it warm in its travel cage and rush it to the vet as soon as possible!! He/She will instruct further care.
