Does it ever make you sad in summer to see your kitty longingly staring at the great outdoors? For some people, having a cat who never gets to set a paw in the green grass or bask in the sunlight is simply too much to bear.
While building an outdoor enclosure for your cats may take a little more time and effort than the average DIY, it'll all be worthwhile when you see your feline friend frolic, stretch out on the grass and watch the birds, safe in the knowledge that no harm will come to them.
Start by deciding where in your garden you want the kitty enclosure, and how big it can feasibly be without detracting from the overall ambiance of your backyard. To that effect, you may want to place the structure close to a big bush or some foliage so that it is somewhat camouflaged.
If you have a particularly small garden, it may be a cool idea to build an elevated tunnel that runs along your fence. This will give your cats the chance to run around and explore a bit, without taking up too much valuable entertaining real estate in your yard.
You can buy a cat door specifically made for windows, so if you choose to build a cat run, the kitties can exit of their own accord. These cat doors can get a bit drafty, so in wintertime it may be best to take them out.
Another option is to install one of these cat doors into a low lying window, and then build the structure attached to the side of the house. This could be a great option if you don't have a fence, and don't want to build a stand-alone cat enclosure in your garden.
Simply using wood and chicken wire, you can create a multi-tiered outdoor playground for your cats, and spruce it up with a log or scratching post. They can be as simple or elaborate as you have time or space to manage - even a little kitty outdoor window box would likely make your feline friends happy!
