Hello. I'm new to this forum. I have a lovely new male hedgehog. Not sure of his age but he was 6 inches long and weighed 12oz when i got him. I was told that he was a few weeks old but I think he is a lot older. However I find that his hair on the bottom end is rarer bare. Is this normal? I can see his pink skin. Sorry if this is normal and I'm worrying over nothing. :?
