That would figure, along with her really tiny stature.She may not have gotten enough taurine when she was younger. It is vital to healthy neurological development.
I hope she is able to blossom now with all the space, love and care she will have in her new home, and yes - when the time is right be able to move on to some other new home where she can be treasured and made to feel as special as she deserves. Fingers crossed for her and hoping your vet thinks she is in reasonable shape and not pregnant when you are able to take her along for her check-up @sweetlynn86.
