Ok, so I'm not a newbie but I'm having an issue that no one seems to be able to help me with.....

I have a pet that is an adult and is a captured pet, but my mutators will not work on her. The use button doesn't even turn blue when I click on the mutator. Could someone please shed a little light on my situation!

This is the pet:

UPDATE:
Someone else offered to try an mutate her and it worked for them. I still don't know why it won't work for me. She has now been mutated, but the issue still stands. -_-
