Do you live anywhere near a PetValu or PetPlanet? Or any specialty dog/catfood place? The big thing in foods now is grain-free...there were a gazillion choices at both of these places and all would fit the Protein/Fat/Fibre ratios for hedgies...an entire bloody store of them...I was there forever...
I am feeding Snarf NOW! Sr Weight Mng't, as well as Arcana Grasslands and Nutrience Duck, Fish & Brown Rice (they're both higher in fat -20%)...maybe there's something similar in a low-fat version?
The Acana is especially good (34/20/3%):
Lamb meal, sweet potato, de-boned lamb, peas, de-boned duck, fresh whole eggs, sun-cured alfalfa, sunflower oil (naturally preserved with vitamin E), fresh walleye, pumpkin, fresh Northern Lake Whitefish, red delicious apples, carrots, turnip greens, organic kelp, organic bladder wrack, organic dulse, juniper berries, cranberries, Saskatoon berries, blackcurrants, angelica root, chicory root, red clover, red raspberry leaf, dandelion root, peppermint leaf, marigold flowers, chamomile flowers, rosemary extract, Lactobacillus acidophilus, Enterococcus faecium.
There's no crap in it!!! I balance the extra protein/fat with other foods that have less.
My point is: these stores had many, many chocies...terrific canned food, too! And the staff at both offered to get more samples in and order in what I wanted and said I could return anything - even if it's not going anywhere near a cat.
