appreciate all the advice.
With regard to food though....Twiggy's weight was perfect before Nuda came. She was fed thrice daily for 6 years and had access to kibble all day long. She never ever finished the kibble in one sitting... she would nibble on 15-20 kibbles, 3-5 times a day and still maintained Perfect weight.
(Sphinxes, from what I've learned over the years are often fed more often because they get cold so easily..) (Not sure this has anything to do with it...but just as an FYI, Twiggy is toothless)
The issue is now. The issue is the fact that not having her nibbles... THAT is what is causing her stress and is changing her food eating behaviour. That is what is causing her to gorge and gain a bit of weight.
Given that the way Twiggy was eating worked 100% for her, Doesn't it make sense to try to emulate the old situation....versus all these new ideas? She's gonna be 13 soon.
