I want a thermometer for my cat but I really don't wanna have to take his temperature rectally if possible (I mean I will if I have to of course). Are there any others that I could use?

Hi there.  I found the pet thermometer below that can be used on cats.  You can take the temperature by the ears.  I'm not sure how good it is.  I know you can do the same with babies and it seems reliable.   I hope it is as if you are thinking of taking your cats temp via the rectum I would recommend you take him to the vet for the vet to do it or the vet assistant.  I really hope your cat isn't seriously ill and that he feels better soon.

Hope this helps.
