Sweet pics, thanks for sharing

My guesses on genetics...

1. Beige Baldie
2. RED(Red Eye White)
Blue Variegate w/Possum Blaze
3. Black Double Rex
4. Ruby? eye blue I think ~ Blues carry all of the red eye recessive eye colors, pink, red, ruby. but they are predominately black eyed rats.
Blazed blue rats tend to have red, ruby or pink eyes, but not always.
