When Cattro gets like this I have figured it's either her CRF making her nauseous, or the fact that she doesn't deal with hairballs that well in her old age. Sometimes she will vomit and eat poorly for 12 days or so then out comes one big hairball and all is well. Could be a combination of CRF and hairballs too. Glad Sophia is eating - I resort to all sorts of tricks to try get Cattro to eat.Small amounts of butter, Philadelphia soft cheese, hoummous, plain yoghurt, raw mincemeat are her best . When she is this bad i can't think of carbs, she must eat something.
