That is a possibility in a couple years or whenever if he starts to suffer. For the last 7 weeks, he has been eating, playing, running and back to his old self. He had dropped to 4 lbs back at the third week of May. Now he has gained since he has started eating again. He is at 5.2 lbs and still gaining weekly. It is just so odd that his numbers were so bad and he was so weak and he mysteriously pulled out of it. I have no idea. Maybe his guardian kitty angel was watching over him.
