Hideys with Floors

[Starwind Amada]

Do they make hideys with floors? That way I can just pick up the hidey and grab the pigs since they'll have nowhere to go.

Yes, here are some linked from Etsy (hopefully these links are fine to post?) :

Homely Fleece Hidey | Nordic Nature
Guinea Pig Red Fleece Toadstool / Mushroom House Bed
Baby Unicorn | Guinea Pig Bed | Small Pet Bed | Hidey Hut | Cage Accessories | Fleece Liner | Pee Pad | Piggy Pyramid

Another (and cheaper) idea, if you have the time, is making a DIY hidey. Below are two tutorials from YouTube.

Or just use a small box or a cat carrier as they have a door on the front which can be closed to fully ensure they cant get back out!

Or a fleecy hat!
