I got this momma cat named snuggles from a close friend that just nursed 12 kittens (not all hers). I also took one of her kittens, Tina. Tina is almost 13 weeks old and Tina still tries to nurse :/. My vet told me to separate them for awhile. I had Snuggles to go get spayed and while she was in recovery at my place, I had Tina go stay at my parents. About a week later Tina came back and she is still tries to nurse. Snuggles growls and hisses at Tina, but I do not think Tina gets that she needs to stop. Should I send her back to my parents for a little bit longer? Any ideas please??
