What funny habits do your pets have?
My cat likes to shower with me. He will sit and drink the water as it runs until i use shower gel, then he will sit on the edge silently judging me for contaminating our lord water.
My dog likes to sit in the bathtub during the summer, most likely because it's cooler than the floor or her bed. Totally harmless unless you're going to the bathroom in the middle of the night and think there's a killer in your shower.
Kody, The Chocolate Lab
Growing up, we had a chocolate lab named Kody. Kody had a few oddities and idiosyncrasies about him. My parents are beer drinkers, and Kody would learn how to open each and every cooler we ever had so that he could eat all of the ice. That dog LOVED ice, he would eat it until he had what we called "brain freezers".
I have a giant Maine-coon Siamese mix tomcat. His thing is to bring up laundry from the basement during the night. The weird thing is that he's pretty good at taking clothes into the right rooms. I don't know if he does it by smell or what - but it's pretty normal for me to wake up to a pile of my socks, my daughters some of theirs, etc. He also chirps and meows the entire time he's making his deliveries - which is pretty funny in and of itself.
...The Fart Sniffter
My dog can sense when I'm about to fart and will stick his nose near my ass crack to smell it and then run away in disgust after. I have no idea why he continues to do it when it clearly annoys him
Lola, The Farter
My SO's dog, Lola, farts when we enter the car.
Loving You Slowly
My boyfriends cat loves to snuggle up on people's chests and then slooowly and veeery gently place her paw (with claws out and toes spread) and just .. place it on their mouth.
