I got home last night around midnight and while attempting to stimulate for urination, I noticed his penis was engorged and had a hematoma at the tip (from the other one suckling, I presume). With slight pressure, I as able to get a substantial stream of urine to come out. He seemed fine. When I woke up this morning, he was on top of his blankets, not snuggling with the other. He is lethargic. I'm assuming his penis might be infected. The only antibiotics I have right now are 875 mg Amoxicillin.
1. Should I administer antibiotics? If so, how much?
2. Is there a specific way to help relieve him besides lightly squeezing the penis?
