I have 4 cats in the house.
My girls are mother and daughter. When I got mom she was within 2 weeks of delivery and since both have been spayed. Their ages are Princess 8 years and Muffin 7 years. Princess still lets Muffin nurse.
The newbies are little toms that I found abandoned at work Saturday. Vets best guess on age is close to 3 weeks. They have some problems; but with love, care and grace they will grow up.
