Charlie and Garrus have been best buds since the summer of 2017, just before we brought them home as fosters. They see each other as belonging to the same “social group,” groom each other, play together, and snuggle together. Charlie often uses Garrus as a pillow, which apparently, Garrus doesn’t seem to mind.
But look at this! Garrus’ position as Charlie’s pillow has been usurped by Mau! Scandalous!
I can tell you that all three were making happy kitty sighs. Charlie was nearly snoring with contentment. You can actually see him smiling in his sleep too.
