Rank animals based on intelligence

This afternoon L. and I were debating which animals were smart and which were not.

Now before I offer L.'s ranking, I will preface this with the scenario going on at the time. Our foster puppy, a very active and friendly 6-month-old black lab, was sitting on the living room floor licking his genitals. He does this "about 100 times a day, every day," according to L.

So with that said, and the fact that L. has first-hand experience with each animal on her list and clearly has an affinity for a particular type, I will share with you HER ranking of animals based on intelligence as she sees things...

#1 - Pigs
#2 - Cats
#3 - Dogs 
#4 - Sheep
#5 - Chickens
#6 - Ducks
#7 - Guinea Hens

Pigs are at the top of her list because...

"They know how to cool themselves off with mud."
"They poop in the same place all the time so they don't mess up the rest of their space."
"They know when you're coming to visit them even even when you're sneaking up. "
"They are always happy to eat. "
and...
"They don't sit around and lick their private parts all day."

And just for the record, G. our family's true dog-lover, did not agree with this ranking. Although she did concede the last point was a good one.

When it came time for G. to do her list, the debate about the cat ranking between the sisters went like this...

"L., cats are not smarter than dogs. You can't train a cat."

"Yeah I know. THAT is what makes them smart!"

G. conceded that point as well in her own ranking. And added a couple of other animals she has first-hand experience working with on a regular basis.

#1 - Horses
#2 - Cats
#3 - Dogs
#4 - Pigs
#5 - Chickens
#6 - Cows, Sheep (a tie)
#7 - Guinea Hens
#8 - Ducks

And I do have to laugh about the sheep ranking. They are awfully cute but L. & G. will tell you that, "they're just not too bright." It doesn't mean L. doesn't love her sheep, she really does, but it is amusing that she's come to the realization (as many farmers of sheep will tell you) that they just aren't too smart about anything.

How about you? How would you rank the intelligence of the animals in your life?
