I don't think a vet visit is necessary at all. I think that Twicket of yours had a little talk with Lil Miss Polly Paws and told her she had to change her ways or else she would have to deal with him. He must have told her "look meowmie is having a rough time and I am here to make sure you guys do everything you can to help her out and you part in this Polly is to be nice to meowmie and let her know you really do love her"

Smart boy that Twicket. Good job buddy.
