First season for Jessie?

The last couple of days Jessie ate less then normal. Also the boys like to smell her more. And yesterday she peed inside, like an accident pee. Although a little young it is possible that she is at the beginning of her first heat. Feeling a bit 'under the weather'. We have made een plan to make sure that she won't get pregnant, but we wait a little bit with that. We keep her close and when the boys are around we don't let her out of our sight. Later on we will keep them apart and walk them separate. A whole operation but necessary. Hope that Jessie will get her appetite soon.
