OK, I'm trying to figure out if I have a problem or not.

I have two unrelated neutered male cats, each about a year old, that i
adopted from the local shelter about two months ago. both domestic
shorthairs, nothing exotic. they seem to get along fine, and haven't had
any major problems adjusting to their life here.

but at times they have cat wrestling/chasing matches which can get
pretty wild. yowling and even spitting, to the point where i have to
break it up b/c i'm getting worried. when i do that, it's no problem, it
doesn't seem like it's a full on cat fight (i would never break up a
wild catfight, for my own safety! but these, I can just holler and reach
in and seperate them. they look at me like "why are you spoiling the
fun?"). Five minutes later, they will be asleep together on the cat bed,
or grooming each other, or otherwise happily interacting w/ each other.

The problem? Healy has scabs up and down his body from this. Nelson cuts
him up pretty good. I have tried keeping Nelson (and Healy) trimmed
pretty close on the claws (no they aren't declawed), but it doesn't
help, and I see Nelson biting, too (but neither of them have *ever* been
aggresive towards me or any other human). Healy doesn't appear cowed in
any way by Nelson, it seems to be 50/50 as to who is chasing who. And
like I said, they sit happily together most of the time.

But I just got worried when I pet Healy and feel all these scabs. Do I
have a problem here?

They are together -- and I'm sure wrestling like mad -- for much of the
day while I am at work. I would hate to seperate them while I'm gone,
that's the reason I got two, so that they could keep each other company
while I'm gone.

any thoughts? suggestions?
