So I have had a few things come up with my boys lately. First off is that Romeo's toenails appear thickened and misshapen. He is coming up on 3 years and I believe it to be caused by him not being very mobile anymore. They kind of curve over.

That aside- last night I had Romeo out for cuddles and Ensure, and he's covered in scratches. They look like what would be caused by teeth and are along his shoulders and back. I saw him and Louis wrestling yesterday, and Louis was being some what rough, so I imagine that is when it happened. Louis is 6-8 months old now, so if there will be aggression I expect it will show soon. I don't know if I ought to separate Romeo or not. I'm afraid with his age it could be too hard on him.

And, when I gave Romeo a once over last night after finding scratches, I checked inside his sheath. He had some stuff caught around his penis (looked like dry semen) which I gently wiped off. It smelled awful, like fish. Can I clean his sheath with something or should I just leave it be? There's nothing wrong, just smelly dry semen. Ew! I was thinking either plain water or saline.

Saline solution should be fine. It would give it that extra clean than just plain water. I wish I knew more. :)

i agree with pitterpatter, unfortuntley all males that get old start to have issues lol and my old male rat had about the same problem in 07, he never bathed himself anyways but when he got older it was terrible! he had an infection in his sheath, i had to drain it and use proixcide and warm water and a little qtip to et everything out and antiboitics. silly boys! the stuff we do for them lol as for the toenails i just used a nail file to shape it, he must have damaged his nail bed. my old rat Tug did that too. i would personally seprate them unless u r around to stop him from being bullied :-( Sparty has been buling Roxy really bad recently so they r on break hehe :-) i hope your boy is ok Kins!!
