Welcome to the wonderful world of Sphynxes!!

Sphynxes are notorious for being verbal. He's gone through some changes recently (change of home, person). Sphynxes are VERY loyal cats that form strong bonds with their humans. Try putting nightlights out. I would also have him checked out by the vet to make sure there are no issues with his hearing.

As far a suckling goes, MooShoo did that for about a year. Sounds like it may be a trait of the Sphynx because I've never heard of any other breed of cat doing it.

When I first got MooShoo, he cried alot too. I attributed it to missing his littermates, seeing as he was a rescue along with 5 other Sphynxes. Now, he sleeps right next to me, under the covers with his head on HIS pillow. I would say give Ducky some time. Your house and persons living in it are all new to him.

Poor Ducky
