Runt kittens are likely to have congenital defects and decreased nursing ability. Due to this, many of them will not survive at all. Still, with proper care, runt kittens might survive and even gain normal weight.
If the runt kitten survives, it might grow up to be a healthy cat. Some people will even like cats like this because of their size. If you want to give a lot of love and affection to a cat – you should definitely consider a runt cat.
