I'm currently fostering a lovely, agouti French lop boy who was found as a stray. He has mites which are being treated and is on Ceporex for infection in his back teeth, which are also in a bad state. He is eating for England (SS pellets in particular, 3 meals a day!) and loves his greens but so far his weight seems to be going the wrong way Any tips on helping him to bulk up? Thanks!
