What does your vet say ? It's best to check out everything in case there is a reason he is not putting weight on , Lottie is quite thin as she is allways on the go I can feel her little ribs but they dont stick out so I dont worry about her too much as she eats but if your little one is not eating he may be a little underweight, it may give people an idea of his stature if you post his photo on and his weight details.
