This is Ares and he's 3 1/2 years old. He also suffers from Hind Leg Degeneration, which means that his back legs don't work real well any more. Sometimes when a rat gets this they won't be able to move their back legs at all, Ares can still scoot his back legs a little but he drags himself around now, instead of walking.
I wanted to help out other rat parents who might be dealing with this so I wrote an article. If you'd like to read it, just click on the link.
I hope it helps any pet parent out there who is dealing with this. Any animal can get Hind Leg Degeneration and it's good to know how to care for them when they can no longer care for themselves.
