Souraya,

I'm suprised that the Vet couldn't tell if she's spayed.
Does she have very dense, thick hair? You should be able
to see a scar on her belly if you she'll let you rub her fur.
Do you think she's sweet and submissive enough that
Drake would accept her as part of your "pack"? Liz.

p.s. Another reason for her being so friendly, is that she
might have been dumped after being befriended.
