Grumpy is a kitten that cannot meow. She's mute and can only hiss or spit. This makes her extreme hostile as she is aware that she's not like his other siblings. She doesn't come out to play, but she can definitely walk. She retreats to corners and can stay there for hours. She's extremely fierce and we had yet gotten her trust. Potential adopters can come and visit her first before deciding to adopt her. But, I can assure you that she is the most beautiful one among all her siblings. Her posture and eyes are mesmerizing.
