Always used to worry me that when I had electric cookers - one of the reasons I'm so firm about cats not going on kitchen surfaces.
If it was a few days ago (which I'm inferring) she should be fine if there are no obvious symptoms by now - and you may have an easier job than many here on training her not to go on surface in the future!
My highly intelligent kitten decided that the very best place she could walk was over the cooker hob which I had just turned off. Tried to stop her, but didnt get to her in time.
She ran off and when I checked on her the pads on her paw were redder then the other ones but didn't seem to mind when I touched them. Tried to run her paw under cold water but just got gouged for my troubles.
She seems ok, she is putting weight on it, walking without a limp etc, not meowing or seeming in pain. Is there anything I should do or am I overreacting and she'll be fine?
