I can't remember how old you said that Grr is but I foster lots of very thin cats for the local shelter. At first I used canned kitten food alot for extra calories but with respect to an older (+10 years) cat, my vet said that the high protein content in kitten food was not good for an older cat's kidneys.
Although you aren't interested in useless calories, for very thin cats, I supplement with some Nutrical which you can get at the Pet store cheaper than from a vet, several times a day. My experience has been that Nutrical is something of an appetite stimulant. Or maybe it works that once an emaciated cat starts getting a threshold level of calories, their appetite starts to kick in again. After looking at the calorie content of foods and trying lots of things, I usually feed Hill's A/D (from the vet) which isn't so extra high in calories but is apparently very digestible and high in nutrition, Nutrical, and meat baby food as a supplemental treat to start putting weight on cats. Extra bits of nice chicken or other meat in between meals can also be a help. _______________________________________________ Felvtalk mailing list Felvtalk@felineleukemia.org http://felineleukemia.org/mailman/listinfo/felvtalk_felineleukemia.org
