Oh man, I just saw this thread. As a sav owner, I am just sick over this... Thanks for taking such good care of him. If the crickets seem like too much, you may try eggs. Esham loves his eggs. I boil them just like you would for a human. Some people give them yolks, but I remove them. You can cut them into bite size pieces. The smell alone is enticing for them. They have protein and fats, so it should help him bulk up without being too tough. In fact, it might be a good idea to give him yolk. (One of the main reasons savs die early is from obesity..). I have never seen our Savannah drink, so good for you for getting him to drink.. Give him a nice, big water dish, they like to soak on their own, plus they poop in their water, usually. So, of course, you would have to change it daily. Also, they have locking-type jaws.. I mean, sometimes, Esham gets a hold of his leash and it's a fight to get him to let go. They have crushing jaws, so force-feeding is going to be a pain..
He looks so sickly; how is he doing now? I would take him off your hands in a heartbeat, but California is a bit far
Thanks so much for taking care of him. We have had our monitor for almost two years, so I can try to help if you have other questions.
