This may be a weird question, but for those who have grey striped cats, does your cat seem like his or her face gets more square at different times? I SWEAR wilber's jaw gets squarer when he's really happy from being petted and starts purring loudly and we're head to head snuggling. It's almost like it changes shape. Am i imagining this? I always tell him it's the tiger face, cause it reminds me of those square faced tigers that are all one color, I don't know what kind they are - it's a beige color. Maybe it's me or maybe not and it may not just be the grey striped ones, but I've never noticed this on Oreo.
