I'm a bit lost as to who Lily is, sorry, but my opinion of this guy is no way! What the heck does he mean by "it present working condition". Sounds like he is looking for an animal to breed or something. Sounds shady to me. With all this talk of final asking amount and and buying it he doesn't sound like someone wants to "adopt" a pet to me.

I think if he keeps persuing it I'd just tell him that you are looking for someone who isn't so concerned with costs and more interested in the animal itself.

If I wanted to adopt an animal on petfinders my first questions would be about the animal's personality, health and so forth.
