Question about Spayed Females

I have an Oriental Shorthair who is a retired breeder, as a kitten she was Best OSH Kitten at the International Show, they had 40 or 50 OSH Kittens that year so we are really proud of her. Then she stayed home and had babies. Now she is a tad bit fat and we are trying to get the weight off her, she seems to be loosing weight and is starting to look good. She seems to have a sagging belly, it looks like her teats filled up with milk and never really "deflated". Is this a normal thing? I usually get my cats as kittens and they are spayed before they ever have kittens so I am not fimilar with this. Is it just pockets of fat or is it just normal desended teats?

MyEx Queen Loonie Toones still has 'bulky' nipples and a big fat sac!

This is common and not just in altered cats. All my boys have sagging bellies. Guess its because they are LAZY!!!!
