So I'm taking my little guy to the vet on Wednesday to check for a RI. He's pretty heavy in shed, he went into blue yesterday, still really cloudy today. I let the vet know that he'd be in shed, in case that's a problem or in case she thought we should wait but she suggested bringing him in anyways.

Basically I'm just wondering what the best way to transport when it's chilly out. It has been super warm but the temperature has dropped enough tonight that you can see your breath here.

I don't have any heat packs, but I was thinking putting him in the container he was shipped in (if he still fits.. if not I'll just put air holes in a bigger tuperware container) and putting that back in his shipping box, toss in a jar with hot water in it to keep the box warm? I've never had to take him anywhere, so just wondering if this set up seems sufficient or if there's a better way to do things.

Thanks guys
