[PlayingPretend]

It's important to remember that you did all you could do for the circumstances that were offered. I remember my mother was once caring for my half-sister's rats and left them in the car for a mere ten minutes and they overheated and both of them died. =/ And I had a close call with mine... I felt guilty for that for ages (live and learn), but in your case, there wasn't much you could do, yanno? Not if you weren't allowed to bring your mouse into the house. I realise how hard it can be to lose a beloved pet, even a small critter like a mouse. <3 Perhaps you could do a special ceremony in honour of him? Like write a letter to his spirit/to help release his spirit? If you're into that sort of thing... Or maybe you could have a special burial. Though it's bittersweet, sometimes having those sorts of memorials can help me feel a little bit better about the situation and a little less guilty when I feel at fault. <3
