The male reproductive gland that is missing in the cat but present in the human is the seminal vesicles. In cats, a small prostrate gland surrounds the point of entrance of the two ductus deferens and the adjacent urethra. At the caudal end of the pelvic canal, a pair of Cowper's glands enter the urethra canal. The male cat does not have a seminal vesicle as the case in human male.
They would know if they see anything like traces of water or anything else that would be nessecary for a living organism to have. They look for these with technology like the hubble telescope as well as the drone on Mars to gather as much information as possible.

Hope this helps!! :)
