i guess i am in similar position. So confused, not sure what to do

about a week ago i saw an add in gumtree (if i remeber right) bengal kittens for adoption, so i replied that i am interested etc and ask a bit more info about kittens. i received reply yesterday saying that kittens are still available and they are free to good homes and they are vet check and excelent pet to children etc. So i email again asking if i could come and see kitten and i got reply just now saying please give me your full adress and i will deliver kittens to you tommorow. I am not sure what to do- something dodgy, why i can not see kittens, why she do not answer to my questions about kittens age, sex etc...

cat is a live creature and i do not want to commit for something i even can not see. is it normal kittens owner behaviuor or is it just me being paranoid
