Sounds like more of a seizure than heat stroke...body temps will rise dramatically during a seizure (if it gets too high for too long a period of time, the brain can be damaged...you were right to get her cooled down asap). And given the fact that rats and mice are tumor factories, your guess is probably a correct one...I bet she seizured because of it! If it happens again, you may want to consider euthanasia or feeding her off...![]()
