Wendy;
The thermometer that goes in the ear is used with kitties too but ussually gives a lower reading. My fp takes both ear and rectal temp, never asked why the do the ears if it isn't too accurate but thre must be (hopefully) a reason.
If you lubricate it well, rectal temp taking should be no problem. Is it just you taking temp? When I get a squirmy one I've somebody to help because you're right, if he moves suddenly it could hurt him but generally there's no problem.
