Well, as I've already posted here and there, Nibbles now has his very own sand bath using the packets of chinchilla bath sand mentioned above. Its been amusing to say the least! He wasted no time in checking it out and dug and scratched in it like crazy then half rolled around it in. (I'd still like to see him belly up with feet in the air!). I was hoping he'd continue to just use it as a bath but he now uses it as a potty and seems to have abandoned his proper potty in the other corner! Oh well, so I have to clean it up a bit more often. He's having fun obviously but I'll never understand why he has to take a nap in it!!! Weird. I saw him in the jar just last night right after he had been running on his wheel - of course the first time you see your hamster in a new "jar" just lying there motionless got me concerned so - head to the glass I looked for breathing. Yep, he was alive, taking a nap! All this running around in his new larger tank I think is tiring him out LOL! Poor baby! Well, one good thing came of this - I know where his nose touched the glass and his bottom ended, basicaly filling up the jar, so I measured it and he's about 61/2 inches long! He's almost 4 months old. I have got to weigh him again. He was 2oz when I got him at about 21/2 months old and half the size. He's grown a lot!
