That's absurd...it's skin and bones...I would have been really tempted to give "management" a good throttling...surely there's somewhere you could report this. That's got to qualify as mistreatment or cruelty or something. I've seen some pretty pitiful pet store photos, but that takes the cake.

I don't know if it would do any good, but that's the website for the ASPCA in NY. Mouse over the "Fight Animal Cruelty" tab and click on "Report Animal Cruelty".
