If you are like me and think that mice, rats, voles, and the like are cute! You probably either would own or want to own one, if you thought the above was true. I like catching wild voles for pets. We have managed to catch one so far, and I hope to catch more. look for the burrowing under mulch or in fields. Either set humane traps, or go the cheaper way that I do. I find some in the winter runnign around in snow tunnels and I catch them then, or they are easier to catch when you mow down a field or garden, we caught ours, dubbed 'Junior', when my mom mowed down the garden and several ran out. We used sticks to herd it into a bucket, then transfered it into a small cage while we prepared the tank. A good vole house would be a 10 or 20 gallon glass tank with a lid that fits completly over the top, snugly. 5 gallons can be used for temperary houses, such as keeping for several days at a time. The bottom should be lined with gravel, about and inch or two, to keep water from collecting in the tank. Then up until about a couple inches from the top fill it with mulch. The vole will make tunnels in this. Put in a bowl of water, and also food. The food mix that works for me is equal amounts of 2 different brands or cat food, a cob of corn, and equal amounts of bird seed, rabbit pellets, and dog food, as well as cat treats and some hay and grasses. This way there is a lot of stuff to chose from, but high protien food of either dog or cat, and seeds and some type of grasses or hays. Make sure that the water dish is shallow so the vole won't drown. Also, put some sort of hide away in there, I used a old, small, bird feeder gourd, which our vole loves!!! As well as a hide away, put in some cloth and/or fur. They will use this to nest. Also, I haven't put more than one vole together, so you would have to check up on that. These instructions are for a meadow vole. Also, I would be happy to answer any other questions I could.
