The snuggle safes are great and lots of my rescue friends use them, as does the shelter where I volunteer. However, you do need to be careful because the shelter has one cat who was severely burned because the disc wasn't wrapped correctly and ended up directly on the cat. I'm sure you will show the common sense that this cat's owner didn't.

Thank you for taking such very good care of Barney in spite of being stretched for resources. He was obviously in dire need of someone to take full care of him.
