I had a lionhead litter born in November and they are now 8 weeks old. There were five of them, which is a bigger litter size for lionheads. Four of the kits are growing like weeds and doing great. Good weight and everything. But one of the them is half the size of her siblings and very thin. She eats, runs around, drinks water, snuggles and grooms her siblings. Everything fine but she wont grow or put on weight. My instinct is to cull her as I wouldnt be retaining her and it doesnt feel right to sell her to a pet home if something's wrong. But it's hard when she doesnt act sick. She eats plenty of pellets and hay. I could try giving her oats but I just dont feel that shes not getting enough calories, its just like what shes eating, her body isnt making proper use of or shes just stunted for some reason. What are everyone's thoughts?
