I feel a little silly asking this....

It sounds like he was doing what we call the "elevator butt" here. Both my males and females will do this when I scratch their back end towards their tail. Sky really sticks his butt into the air very high. All of my cats are spayed & neutered so it's not a sexual thing. It may be an errogenous zone though because they go crazy and really enjoy being scratched here. I'll attach a picture of Sky showing you the "elevator butt".

yeah my dearly-departed Montego would make funny faces and lick the air when you scratched him in front of his tail. We always called it "goofy kitty face"

No need to feel silly asking this. If your vet can't tell, who can! I hope he/she is more skilled when it comes to illnesses in animals.

My Fister does the Elavator butt also when I stroke him on his lower back - it's quite normal.

Thanks for the replies everyone.

My boyfriend and I are almost 100 percent sure that Proton is a female.

For one-when we looked up pictures online the genitals look female to us
Two- My boyfriend has seen the behavior of a female cat in heat before and
says Proton's is similar. (Sticking the butt in the air even when she/he
being touched, meowing incessantly.)

So, I am going to do some research find a vet and get her/him spayed or possibly neutered...I feel so weird not knowing for sure. But we still love little Proton no matter what!!!

just go to another vet for a 2nd opinion.

Ok can you get a pic of your baby's rear end & post?? Then we can all tell you which it is..

Years ago I had a fluffy gray kitty and the vet told me it was a female. When I took her in for spay, the vet opened her up to take out the female parts - didn't find any. Then he looked under the tail and saw the male genitals. His explanation? "He's got a lot of fur." Poor cat had both abdominal incision and a sore butt.
