I ran a search for "feral cat blogs" this morning and found The Feral Cat Rescue Project.
There is a calendar feral photo available to set as wallpaper on your computer. I like having a calendar in easy view, so I added it to my computer.
Right-click on the photo to save it.
The go to Control Panel on your computer
Click on Display
Click on Desktop
Click on Browse to find and choose the photo file.
Click Apply, then OK
There you go!
