We have a Tonkinese. They are very smart cats and very trainable. Ours also likes hiding, behind the fridge, in wardrobes and under kitchen units are his favorite places.
Ours is very vocal as well and will talk at you for ages, when he’s been left for a while or when he wants the door opening.
Having said all that, he is highly strung. When we had our daughter our moggy couldn’t care less, but it really stressed the Tonkinese out, to the point he was losing fur. All in all it lasted about 9 months.
