4t2 squea‘s Beetle Eyes 2 for Pets - Maxis Match Colors
I love these so I wanted them for my pets as well! I used magical-girl-sandbox’s separates, so you can use these with whichever default fur colors you want (using kahlenas' Shakers and Movers in the previews). They include Nopke’s Left Eye Fix, so remove that mod if you already have it. The colors were color-picked from the swatches in Create-a-Pet:

I also uploaded the PSDs in a .zip file for anyone that would like to use these textures to create alternate colors.
