My piggie JJ has been with me for about 3 months. He came from an abusive home. His weight has been a problem since I got him. He was very underweight when I got him, he was fed hamster food ( when the child taking care of him would let him have it) and very little water, after taking him to get a checkup I started him on critical care. After a few weeks of feeding this to him he became a healthy weight. When I stopped the feeding and kept him just on pellets, veg and hay he posted weight again. I’m not back on the critical care. He eats two 3inch syringe fulls in the morning one in the after noon and 2 at night. He would eat more if I let him. Any advice for keeping the weight on.
