Right now, I am very upset. Two months ago, we adopted...well, rescued a beautiful little calico that was living on the streets near a friend's house. Of course, we took her to the vet as soon as we could get an appointment. The vet checked her over and asked if we had seen any signs of heat. At that time, we didn't. This was about 2 weeks after we brought her home. The vet felt her belly and felt what she thought was a "scar." She also thought our little baby was over a year old. Well, we had her back to the vet on Friday, for a booster shot and a quick check over. At that point, everything was fine. The vet again asked if we had seen any signs of "heat." No, was the answer. That is until Saturday morning. Now, she's in heat. I'm upset, because had I known she wasn't spayed, believe me...she would have been before this ever happened. How long can I expect this phase to last (a week?). Plus, I realize that she can come back into heat every other week. We've called the vet...and can't get in until August 30th. We are, of course, on a cancellation list (in case someone cancels we can get in earlier), and have put ourselves on the list with the other vet in the office as well. I'm just upset, because I know it's better for them to be spayed before their first heat and I feel horrible that we didn't realize she wasn't spayed.
