Hello. I have a new kitten i t about 2 weeks back, she is about 12 weeks old and i also have an adult Female who is 2 years old. I had the older cat spayed a week ago and her temperament has now changed she is a lot more loving to the Kitten, but the kitten has now started suckling once or twice a day on the big cat. My question is... is that ok? should i let her just go for it? or break em up?
