Thank you!
We tried the first time and it failed, but we plan to try again on the weekend so fingers crossed.
They are currently in a cage at the moment with a divider just to calm things and get use to everything before we try again. Like I said in my comment above, behaviour has definitely improved and is a lot calmer now with more neutral interactions and less agression.
I don’t actually have any cuddle cups, where can I get them from?
I've bought mine from numerous sellers on Ebay/Etsy/Facebook over the years. @Bill & Ted makes some and auctions for charity, @artcasper also makes them
YouTube has tutorials on making them. Here's a link to a thread where various sellers are identified. Members recommended UK and US sites for fleece cage liners and accessories
