I would ask the vet and do only what he/she tells you to do. I have adopted 2 animals in similar shape and my vet said to feed them as I normally would, and let them put the weight on gradually. Overfeeding and supplementing can cause problems in emaciated and normal animals. Growth spurts can cause bones to becomes weak. It only took about a month for my cat to start showing signs of weight gain, eating a normal diet (and some treats!) Also feeding a normal diet allows the body to gradually adjust to handling the nutrients. You've got an animal that's not been getting enough, to overload would surely put a strain on his liver and kidneys. Moderation is the key here, I believe. My cat was so bad, I was sure he would be admitted to the hospital and be put on fluid therapy, and whatever else. I was sure he would die at home. But, he didn't! I got him in January, he was 6 pounds and you could feel every bone in his body. Today, I don't know what he weighs, but in June, his weight had doubled, and you could just feel his ribs and a little fat under his skin.
Good luck and don't worry! |
