Outdoor Kitty Containments

Question
Thank you for taking my question.  I have 3 kitties and they all dearly love being outside in the summer.  My one is leashed trained, the other puts up with the leash and the other always manages to wiggle out of a harness!  I have been looking at outdoor cat houses, but they are so expensive.  I am pretty handy and could possibly build one, but can't decide on how to build it.  Do you have any ideas on a style that could be built, or do you know of a certain brand that isn't so costly...but still a safe retreat? It will certainly make Treble, Ziva, and Rocky happy kitties!

Answer
Cindy,

Your best option might be a cat run.  I do not know what your price range is, but you can look at the Internet to get some ideas of what to build. I would do a google search on:

cat runs enclosures

and get some ideas from the various links specified.

Best regards... Norm.
