Well, I have two other Hollands (one is just under 3lbs and the other is about 4.5 lbs) and Hitchy is in between, but I can feel her ribs and spine more easily than the other two, even though they have similar diets. My vet wasn’t too concerned by her weight, but she did comment that she was on the leaner side. The vet wasn’t convinced that it was parasites since she wasn’t showing any other symptoms other than she could pick up a little weight. The vet wondered if for whatever reason, Hitchy had a slightly high metabolism than my other two, but she couldn’t find any documentation of that for me.
As for the grain, I couldn’t find any documentation online about the nutrition in DuMor Classic Diet rabbit pellets, which, now that I think about it, is kind of strange…. I already threw out the bag that the grain comes in, but when I go to the store I’ll look at one of the bags. I have considered changing their grain before (since I have heard that DuMor isn’t the most stellar), but that’s all that’s readily available in my area without having to travel an hour or an hour and a half. I did find this (Kaytee rabbit food) at Petco, but I don’t know if it’s any better. I’ve heard good things about Oxbow pellets, but I’m not really sure where to buy that around here.
I wonder if it would be as simple as switching her food out for something higher in quality.
