Clue about thestrals in PoA

[anuchillinz22]

Hey, sorry if this was mentioned before, but did anyone notice the 
horseless carriage that Fudge came out of when he was at Hogesmeade 
going into Madam Rosmerta's. I didn't realize that it must have been 
a thestral carriage till Fudge was trying to avoid stepping on a 
pile 
of something that I guessed must have been thestral dung...? Am I 
totally off here, or did anyone else see this?
