Ruby, don't despair over difficulties you're having with Baco's weight.
I think they are like us - thin and too chabby for no detectable reason.
With people calorie restriction does not really work long term as body tries to compensate and slows down metabolism. I'm not really sure how cat's metabolism works and whether we can apply the same rules as to people. And even with people we don't know why something works for one person and does not for another!
I'm struggling with Rocky's weight as well. He is 6.3 kg at the moment but I think he would be perfect on 5.7 kg. He lost some weight since July 19th due to reducing frequency and amount of food so he went from 6.68 to 6.3.
The lowest he has been in recent years was 6.2.
As you know he is on ketogenic diet at the moment, I might still just ever so slightly reduce his portions.
The problem with Rocky is he does not want to move because he is in pain from arthritis but I still try to exercise him as much as he would tolerate. He sleeps all day in the garden because it is so hot! Being occupied with other health problems I have with him I sort of put arthritis problem away for now but I'm going to start doing something about it a.s.a.p.
So, going back to Baco, do you think she might have some health problem which makes her "lazy"? I don't apply "lazy" to anybody because I think it is not fair as I think if a person or a cat does not want to do anything (does not want to enjoy life) might be due to an underlying condition either physical or mental. I'm a bit careful about it as I have a close person who is very up and going and does not understand other people's issues and labels everybody "lazy" hence my attitude to it.
So if Baco does not do much (and Rocky) it will be very difficult to slim her down. I agree with Carol that feeding different amounts on different days might be helpful since Baco is not on insulin and we have no worries about that. There is this method with people (again, I don't know if applying it to cats is the right thing to do) which suggest that to boost our metabolism you could reduce calories for few days then have a feast alternating amount of food so body has to work harder and does not think you're starving on low calories days. Actually I think it should be beneficial to cats as in the wild they would not eat the same amount of calories every day, on some days they would starve until next meal when they catch a prey.
I'm going to try that with Rocky if he stays off insulin (wish us luck

).
Let me know what your thoughts on this are.
