I get where you're coming from re. the shocking charge Cozie. Especially with the added cost of a dental. I reckon a nominal charge, to discourage people who just think, "Free cat, yay!" is a good idea, but £300 seems a bit steep. I could understand if the current owner's fee was to go towards his dental work, but that doesn't seem to be the case. Have you met your lad yet Drink?
Drink, yes, they are nosy little buggers, they like to hinder help with whatever you're doing. They'll hop on your shoulder and ride about, to supervise whatever you're doing. Even epilating. A Flying Frenzy cat toy helps wear them out.
They're very vocal, but more croons and chirrups. And they wag their tails when happy! And mine loves it when I imitate the noise he just made back to him, we can have a 10 minute conversation of err-erngnah! noises (he doesn't miaow).
I didn't know about the website you posted Cozie, but another one is Devon Zone.
They're very child and pet friendly, I have a v. neurotic moggy, (MCat) who spat and swore at him for months, but the little curly bloke (Little Monsieur) never once showed any aggression. Now they're proper bro's. thick as thieves.
As you can probably tell, I love my little alien cat.
