Ah, thanks. We have had a sad development. Took Rusty to the vet. She came home and got outside, but came back in willingly, so I thought that if she wanted to be out I would let her. She spent the next two nights inside and then went out for two nights and then disappeared for 3 days. I was looking all over for her, driving up and down all the roads. Nearly 3 days to the minute she returned.
I am thinking, oh she got lost but found her way home. Good. She stayed overnight and left the next morning and has not returned and it has been nearly 4 weeks. Again, have looked all over for her. She seemed in good shape when she returned after the 3 days, not particularly hungry. I don't know if taking her to the vet so stressed her out that she started looking for a new place to live. I like to think she has found some place better, but am worried. But there is nothing I can do.
