I've had Tigger for about 3 months now, and Nibbles for about 2. The top pic I posted is Nibbles and the bottom one is Tigger. They don't show the differences in the two very well, but Tigger's fur on his back is lighter, it's more cream than brown. He has a lot more cream on his face and what looks like a silver dusting over the creamy bottom coat and brown over coat on his head. Nibbles is more of a reddish brown and has a broader mask, and a bigger head than Tig. Also Tig has the cutest little freckle on his little pink nose.
