Thank you for everyone's suggestions. We will try him upstairs, we just don't have a large bedroom so trying to fit the crate in will be a struggle. @Zande yes it's quite big for him, we wanted to ensure he can fully move without discomfort.

Also, @Zande you're correct, we have been looking for quite a while but we're lucky enough to find this little guy. We've named him Loki and we definitely feel it suits his mischievous side haha.

Thank you @JKent, I definitely think we'll be moving him to our room tonight. Other than bedtime and our dinner time he's been so good throughout the day! So if this makes him more comfortable I will give it a go!! Really appreciate your help.
