Just started a breeding tank (10 gal) with one male and two female mice. I tried aspen and the Care Fresh bedding and both. The smell is evident almost immediately. I have cleaned the tank with dish soap but the smell is still there.

I saw pine horse pellets mentioned. Is this the same as pine pellet cat litter available at Petco? I'm not in a rural area so horse pellets may be hard to find.

If I can't get rid of the smell I will have to try gerbils instead of mice. Any help would be appreciated.

Thanks, JohnNJ
