Thanks for all the support everyone!
I definitely need to work on the crate relationship Coco. Also, I think it is the very tired nipping that I get as redirection doesn't work when he's very hyped. My house is usually calm during the day - that's why i got him as I wanted a companion. DC are also not fussed. DS (9) is scared of him and remains on the sofa out of reach (for now...), DD is 19 and ASD, although has been making an effort and has even taken him to the toilet. So, theoretically, it should be very quiet for him but I've managed to successfully schedule decorators and carpet fitters over the period and that's been very disruptive. It wasn't planned, but carpets are going in now and then it's done. Maybe the very unhappy cats will start venturing out more then.
As I am typing this he has literally just taken himself into the crate!!!!!!! So exciting, although I have a cold foot now...
Bitey I think I put some of those treats on my order. Hopefully it will turn up soon. I put it in on Saturday, so I'm hoping mid-week.
Elphame Definitely a greedy bugger here too. To be honest, he seems fine with the treats I got yesterday. I know they are a bot worried about chews for teeth, but these biscuits are just fish and sweet potato so don't think they'll hurt him.
Ziva thanks for this - I put his dinner into two puppy kongs and that settled him for a bit. I also got a treat ball from Pets At Home which he likes to chase about. I will definitely have a look at the things you've recommended as he is a bright spark and I think he needs the stimulation. He certainly needs the tiring out!
Jabs tomorrow. 1 week until freedom.
