We got a cat off our aunt and named it Phoebe as their vet said it was a girl (and we were going through a Friends phase) My brother and dad looked at her and thought that she was a boy but the vet said she was a girl so me and mum said they must be wrong. Fast forward a few months when we went to get her neutered at our vet and, lo and behold, she was a he. We decided that it was too late and he stayed Phoebe. That poor cat.
I'm willing to bet that my aunt got to of the kittens mixed up or something and gave us the boy instead of the girl, she's kind of spacey at times. Seriously, a boy called Phoebe, and he was a great hunter and really dignified. You'd have to be with that name
