My goodness, how terrible. I am sorry.
Animals are resilient. Chester jumped off an 11ft high deck while he was under the watch of my MIL. He broke a few bones in his foot and had to get put in a cast. He was only about 5 months old at the time. After they got home, they were downstairs in the basement trying to email me pictures, having left him upstairs to rest. They caught that little bugger halfway down the stairs, and he hadn't even had his cast on for more than a few hours! He got used to it pretty quick. He was running around like a wild banshee in no time, his front right leg just flailing in the the wind, lol.
