Luckily her brother is being neutered tomorrow because I persuaded the vet as he is a big boy - they have a policy of not neutering until 4 1/2 months. So by their policy his sister would be pregnant by then! In the meantime I guess I am on incest patrol until tomorrow? Will her early heat persuade vet to spay her? She is howling at doors, people and well...TWERKING ....
