2 day old rabbit after being bottle fed. It's mom didn't have enough milk for the large litter and they nearly starved. They are recovering slowly, but show amazing willpower to make it.
Continuing with the baby gerbil theme, this was my girl Ambie when she was 2 weeks old. She was the runt of the litter and needed a lot of extra care, so she bonded to me very quickly. Sadly she is no longer with us, but I will never forget just how sweet she was.
