The cat's curious.
They are curious.
Not many cats do but i think its to get your sent.
It means there is something about your ear or the side of your head just there that smells interesting. Cats don't do much that has deeper meanings; they are very immediate creatures.
The plural of "sniff" is "sniffs."
to get the males sent.
Yes they can! My dog always sniffs and even eats our cats poo but make sure he doesnt!
Sniffing one's nose while walking by you could mean that the person has allergies, a cold, or is trying to detect an unfamiliar smell in their surroundings. It's a common reflex that may not necessarily indicate anything negative.
because they like to play in it
yes
Im not sure... but I wouldn't be shy in asking him cuz apparently he's into you.
