No one told me I had to predator proof against cats. Our first colony litter was doing great and every time I pulled out a kit it was fat and happy. Somehow though there are 4 now instead of 9. I finally put it together when I found a body on the concrete floor in front of the horse stalls the colony is using. Cats! :angry: I don't know what we are going to do. I might take some screen door mesh and duct tape it along the top of the stall so it drapes down. Then cats won't be able to fit through the bars. They might still be able to jump over though. Warning to colony raisers. Make sure your kits are safe from cats.
