LOL He is adorable!!!
I wanted to mention that Jasper weighed 1.5 when we got him at 11 weeks. He has small parents. His first vet check was good. He will be 19 weeks tomorrow and weighs 3 lbs.
I think your little boy will do just fine. Have you tried putting kibble on a paper plate or towel to see if he will eat from that? Just a suggestion. I hope he starts eating for you soon.
