Great advice Vixenlite
I know it's hard to stick with it especially when they're making noises like your the most horrid slave ever...but stick with it coz it's for their safety and well being in the longterm
When we first moved to our current home our 2 moggies bless, were totally confused but we did what Vixenlite has suggested and it worked a treat i'm glad to say
It'll be a mini adventure for them when you do allow them out too, getting to know their turf and any neighbors they can blag for treats, peeing on new soil etc Ooh the fun they will have is endless and they'll soon settle, being back in England serve em a dish of tea-they'll soon forget Ola and be mewing Hi their good people and Ta-ra folks
