Sadly, my 18 year old leopard gecko has not been very interested in his food the last couple months, and he is starting to lose some weight. I've already talked to my vet about it, and it sounds like he is just slowing down at this point. I know there are several brand/variations of critical care, reptaid, etc... Can anyone recommend one to me? I'd like to get more nutrients into him if I can. I've bumped up his temps a little and started soaking him more often, so hopefully he might be tempted to eat a little more soon.
