Vets trip---If she is loosing weight and peeing in inappropriate places, then the Neive problem may be a problem with
Boots. Good that you are checking her out. Funny, I thought
Boots was a male.
If it is a health problem with Boots, no sense keeping Neive indoors now--she has already done the DEED, LOL!
If Neive and Boots are allowed outside, it is really important you have them both spayed.
