The cats do not do well in their carriers and we usually medicate them beforehand for vet visits. We sealed the windows and they’re good with food and water. I’m not terribly concerned and think they’ll be fine at 2.5 days for sure. I do feel bad going home for a couple hours just to leave them again for my extended family’s christmas plans next week for another couple days but they’ll be okay with each other and by then the weather won’t be so shit. Thanks for your input!
