Cozy Cat Shelters
If you live in someplace where there are a lot of stray cats and puppies that need a home, then you should definitely do something like this to help those poor creatures. Kitties love nothing more than a cozy shelter and you would be surprised how easy it is to give them that.

All you have to do is keep your large water bottles at home instead of giving them away. Cut off the narrow top of the bottle and put something cozy like an old blanket inside and you just created a cat shelter. A brand new home for some stray kitty.
