Thanks. The vet said that since they probably didn't tie there is a low chance of pregnancy. Also, being her first heat, even if they did tie there is about a 50/50 chance that it will even take. I've had two miscarriages the last year, and my hubby and I are doing everything we can to get pregnant. So if Sushi ends up pregnant and we have to spay her I will be devastated on multiple levels. I'm hoping all is well with her though, fingers crossed.
