I need help please!!!!!!!!!!
For some reason Bernard just doesn't seem to have settled into this new house

The three girls are fine, but he cries all the time. I don't just mean a little "meow" either it's a real heartbreaking, sorrowful wail
I don't know what to do. I'm totally exhausted as he cries through the night and I haven't had a good night's sleep since we moved

and he's just not himself.
I thought at first that it was because we don't have a catflap yet, so he was missing going outside........but for the last 2 nights I have left the kitchen window open and have a chair on the inside and one of their wooden climbers on the outside, so he can come and go that way.........but it hasn't made any difference (apart from that the house is freezing!! lol)
He has gone off using the little tray too

I know that he prefers to toilet in the garden, but he used to use the tray at the other house if it was raining or he couldn't go outside. He doesn't seem to want to do that now.
The first night he poo'd in the bath, the second night he wee'd in the bath, the third night I closed the bathroom door and he poo'd on the kitchen floor

He's been okay the last couple of nights since he has been able to go outside tho.
I've got a Feliway plug in on the go and there is catnip all over the house (which he loves) but it doesn't seem to be helping.
He seems to have got much more needy now too. He's okay when I'm there and up and about and fussing him - but when I go to bed he cries and cries and cries.
I'm torn between picking him up and cuddling him every time he cries and ignoring him. I don't want to reinforce his behaviour of crying by rewarding him with a cuddle
please help!!!!!!!!!!!!!!!
