Hi all,
Just wanted to say thank you for all the support and help and kind words.
After 3 hour long discussion yesterday we decided to keep Mr.Presley. For now he will live in cage next to Biscuit so they can see and smell each other and interact. It'll be better for him than totally solitary life in the shelter. He will also get better nutrition and care and love as well. These were main factors that we considered when voting yesterday (yes we held a referendum

)
We would like him to settle and gain some weight. He is a bit underweight and has some getting used to his humans to do. He was precarious wild when we got him. We would like him to feel happy and relaxed ( this is the only pig I haven't seen lounging with legs out

) so hopefully with time and patience we will achieve this.
Short them plan is to let them both cool down and settle. In couple of months we will look to bond them both again, but of course it's other piggies. This means we will potentially have 6 pigs, but that's fine as we will be looking to move to gardened house soon. And that's the long term plan. I want hem to be able to run outside (if weather in Norfolk EVER improves that is haha).
It may be that Biscuit will never accept another pig. In which case we will arrange C&C in such way that she can still see Mr. Presely and his new wife.
That's the plan and slowly it will work out. He cannot go back. We can afford it and we have room for 2 separate C&C for him and Biscuit so he will stay where he will be cherished.
The best news is that
@pig in the city kindly offered to do next bonding for us, so I'm at ease as though I've never met her I trust her 100% with this task.
It is safe to say I am addicted to Guineas. 6 is definitely the limit. Anymore than 3 cages would be harder to clean haha.
P.S.2 Mr. Presley just got weighted and he put on almost 30gramms in two days!! He's also now learn what the sound of plastic bags
means and is wheeking excitedly before food is served to him. I am extatic

I just am waiting for some correx to arrive and hopefully tomorrow we will reset all C&Cs to accommodate him. I was googling different cage ideas and set ups all evening yesterday. Have seen some most amazing cages, custom made in Germany ! They made me drool. Seeing they are 1000 Euros approx, we will stick to C&C I think hahaha.
Love you all and thank you for your help.
