There was a smell coming from the kitchen. Since Velvet's litter box is there, I'm vigilant about any smells and so far, I've been successful in keeping the kitchen smell free. So I caught a whiff of something (turned out to be some food on the floor I'd missed when cleaning) rotting behind the table.
Anyway, the kitten was sitting next to me and when I started sniffing to figure out the source of the smell, his eyes got all wide and he immediately went into alert kitty mode. I thought perhaps he'd spotted something that caught his attention and thought nothing of it. Started sniffing again and he quickly drew back from me and bolted out of the kitchen.
I chalked it up to a case of the feline crazies and went on with my day.
Later, while studying, a sneezing fit came upon me. Kitten happened to be snoozing next to me and kept right on sleeping. But when I sniffled a bit, he hightailed it out of the room.
My cat is afraid of sniffling.
