Dexter, my oldest male (only 8 months) is really ill. He is not cleaning himself, he does not seem to be drinking, and today when I held him his genitalia were hanging out and seemed to be dry. There was blood at the tip. He has been eating very little. I haven't noticed before because he's been blending it in with his bedding. I use wood shavings, but the bag doesnt tell me what type. Should I switch bedding types? Should I put him down. He is only 25 grams, vs. his sons which are each 43-36 grams.
