My little girl was at 4 pounds for a bit but then went backwards recently to only 3 pounds.. The parents that I bought her from said that she was at 3 pounds forever and after I adopted her, she went up one pound but now is back down to three again ... Laylah is 13 months old and my vet said she's just tiny and will likely stay that way.. Shes so small that I put a cat collar on her that has a little wee bell so I know where she is all the time lol
