Build Cat House Outdoor

About half a block from where I live I have a good friend that has a cat and dog. Both the dog and cat are mixed breed and are black and white. Both of them are male and have amazingly similar personalities. Both of them were rescued from the street in a very much similar manner. Though both were found when they were still young the dog "Momo" was found first and the cat "Momo-Cat" was found about 5 or 6 months afterwards. They both learnt to accept each other very well and they both have had a house built outside. When my friend built the cat house he wasn't sure if he should build an indoor or outdoor house. But since Momo had his house outside and both the dog and cat go along so well he decided that they would appreciate having their houses also in close proximity. Both Momo's and Momo-Cat's house is made of Cedar and though simple both are very well made. I think that one of the most interesting things about this canine/feline pair is that they get along well but really don't interact with each other much physically. This might have something to do with the fact that they are both males or it might have something to do with the fact that they were both abandoned as puppy and kitten. Maybe since both understand that they have been rescued and both are grateful they are content with letting the other enjoy their tremendous luck at having been adopted into such a caring and loving home. Their personalities are not at all like another dog and cat pair that live a couple of blocks away in a store. The cat is nice and friendly but the dog is a spoilt brat that sits all day behind the counter in a cushy little dog bed and barks spitefully at anyone impertinent enough to try and pet it.
