Are you absolutely sure that what you're looking at is a girl? They look almost the same to someone who's looking for the first time. Get this:
I bought a chinchilla from a pet store, and they told me he is a boy. I brought him in to a vet about 6 months later for a regular check-up. I found a vet in the yellow pages that said she specialized in "exotic animals"....this was the best I could do in my city! I brought Ninja in, she looked at his genitals, and asked me if I was sure he was a boy. She went and got a book (!!!) and looked again and advised me that my chin is a GIRL. I was pretty surprised but I figured she knows best. I went home and it just kept bugging me, cause I felt like I know my little guy, and I know he's a boy. I called her up and asked her to look again. I brought him in again, went through the stress of traveling with Ninja again, and she looks at him and asks me if it's the same chinchilla! Like, I paid this lady $80 for a general check up, and she's asking me something like that??? She said he definitely is a boy.
Now I've had Ninja for over 5 years and I still question if he's a boy or girl. I have never, ever seen him clean himself. My other guy pulls it right out and has a hay day cleaning HIMSELF,
, but not Ninja. Well, he licks himself but no deep cleaning. Also, Ninja is temperamental and often sprays urine. Pretty much every day when I go to put him back in his cage, he lets out a puff or two of pee (usually I can just smell it, it's not a lot). I think males do this, but isn't it more of a female thing?
I guess I'll never know for sure! Crazy hey.
And just a quick continuation of the vet story: my chin fur bites, and she had never even heard of this in chinchillas. She was trying to tell me that he/she was fur biting as a nesting thing like rabbits do. I had to educate HER!
I question why I even paid any money at the end of that visit.
