Hi & Welcome to YT! Please don't let your little one jump off of the couch and bed, he is very tiny and still a bit young. I don't let my older ones jump off furniture if I can prevent it. Your vet did the right thing giving you Nurti-Cal, due to his size and age. Keep a close eye on him, if he gets lethargic give him a bit of the Nutri-Cal. Good Luck!
