Sweatin' like a pig

A spontaneous game of random animal knowledge arose as we marched up the hill the other day in our raincoats...
Eliza: I'm panting 'cause I'm so hot and I. can't. sweat!
Ani: are you a dog?
E: yup!
Mama: I'm rollin' in the mud 'cause I'm soooo hot and I. can't. sweat!
Ani: oooh, are you a pig?
M: yup!
Eliza: I'm lickin' my arms 'cause I'm soooo hot and I. can't. sweat!
M: you're a kangaroo!!! ok, ok, I got one...(sotta voce)  I'm peeing on my legs 'cause I'm sooo hot and I. can't. sweat!
E and A: ooooooh, you're a vulture!!!!!
Yup.
