In addition to the 5 humans, there are 3 dogs, 2 cats and 12 guinea pigs (the dogs and cats get along fine, luckily). There isn't a lot of room in the shelter so we have to cram in. We didn't have many threats from disasters in Reno and all of them came with plenty of notice, so I didn't concern myself too much, other than having a plan for evacuation. Here, they strike without notice, so we have to have a plan. Getting us, the dogs and cats to the shelter is easy enough, but what about the guinea pigs?
I have 2 carriers that can fit 2 pigs in each one long enough to get them downstairs and we can get the other 2 larger carriers very quickly, but it's awkward and we still can't get them all down at once. There's also the problem of how to house them after we get them into the shelter and how to keep them safe from the dogs and cats as well as the storm. I need a better plan and I have an idea that I'd like to get opinions on.
Part 1: I am going to get enough small animal carriers to get them all down there in one trip. With 5 of us we should be able to carry them all.
Part 2) I am going to convert part of the shelves in the shelter into temporary cages for them. Take a look:

There are actually 2 columns of 5 shelves, but the picture only shows the 6 I need and they are at the top so the dogs and cats cannot reach them. I can easily make cage doors out of the extra pieces of the collapsible pens I have. I am also going to store extra bedding for them. I will also need to come up with a way to keep at least a days worth of hay in there and make it mouse proof. A tote won't work by itself because mice can breech them fairly easily. I was thinking of using those vacuum sealed bags inside of the totes. That way the smell of the hay will be masked and there's a double layer of protection. What do you guys think?
