I have rats! 7 of them, 3 boys and 4 females...
Neptune and Enigma
Zion, all 3 boys are brothers.
I had to include that pic, it is one of the better ones!
The 2 girls, Angel (beige) and Athena (black).
Caoimhe (pronounced key-V-UH) and Murine (pronounced mer-N-uh)
Tanks are very bad for rats, I noticed you live in the U.S alot of people here swear by martins

The boys are in a R-695 martins rat cage (30inches long, 18inches wide, 36inches tall).
If you can find it, Yesterdays News is very good at odour control, It's pelleted recycled news paper. It's basicly cat litter (use the non scented kind)
