When I get anywhere near her vent she gets very agitated and squirmy......
wrap her up in a towel so she don't fight you. put on a glove and lube it up with a very small amount of vaseline and check her vent for an egg. yes it sounds gross but will help you determine if it is eggbound. be very careful. if you do feel an egg do the epson salt bath till she passes the egg. or get her to a vet if that is feasable
