Our cat liked getting on a sofa to look out a window. Said sofa was getting cat fur all over it and clawed up. Made our cat her own personal window perch for cheap.
Step 1: Long story and parts used.
In the living room area there are 2 windows and one of them has a sofa in front of it. The cat would lay on the back rest of the sofa to see what all was going on outside (damn birds). I had some boards that were part of a shelf in one of our closets that were collecting dust, so I decided to see if I could build a shelf under the other window for the cat to rest on.
Some of the things I did have on hand were the 11.5" wide boards, some black "automotive" carpet and various wood screws.
Items I had to go out and purchase:
Two 8ft 3/4" PVC pipes.
Ten 90deg elbows.
Eight "T" fittings
Step 2: Sizing up the cat
First thing was to see if the cat would fit onto a 11.5" width board. To do this, I put the board on the floor and plopped the cat onto the board... to which end she would just walk away. So I took a piece of newspaper (ads) and put it on the board and pretended to read it.... 10 seconds later the cat lays down on the board and is a good fit. I figured 22" length would work out.
I cut 2 boards out, so they are 11.5" X 22". Since my cat is old and fat, I figured I should make the perch with a lower level to help make it easier to get to the upper level that is at the window.
