Mini Rant + Suggestions needed.

"I'm sorry but I gave you very specific instructions on how I wished you to care for my pet. Because you failed to follow through on most of the instructions, put my pet at risk with a dangerous set up, allowed my pet to become ill and did not treat the illness, I will not allow you to care for my pet again. You may tell your students that until you can follow the instructions given, you will not be displaying any of my animals again."

Since you went overboard with specific instructions, to make it as EASY and FOOLPROOF as possible and he failed in so many ways, I would not really attempt to sugar coat much of anything.

You could also point out it was the equivalent of him taking your dog and tying it out in the sun without water or food for 3 days while it was sick. 3 weeks without food isn't a big deal, but unregulated heat, untreated RI, no fresh water, filthy conditions... that's neglect and endangerment.

On a side note, I've ALWAYS ended up regretting every single pet I've sent into a classroom situation to date. Every time, they say "I'll do it right" and every time the animal ends up in a poor situation, underfed, without proper heat, unregulated heat, dirty or no water, dirty caging... EVERY time. I'm sure that there are wonderfully responsible teachers keeping classroom pets in flawless conditions. I sure haven't encountered them myself yet.
