This rainbow cat periodic table is an update of the original Cat Periodic Table wallpaper.
There were some requests for the atomic weights to be added to the cats. Each cat now contains the atomic weights in addition to each element’s number, symbol and name. The different cat shapes represent different element groups.
Another request was for different background colors. Enjoy!
There is also a PDF version available for download and printing. Choose ‘fit’ and ‘Landscape’ for your printing options.
If you don’t like my background choices, a transparent PNG image of the Cat Periodic Table can be found here.
EDIT: These wallpapers have been updated to correct the atomic weights of iron and gallium. The updated cat periodic table wallpapers can be found at Cat Periodic Table Wallpapers – 2015.
