I think there has been some great advice already posted, I have two boys atm who both came from farms originally so were not particularly well socialised as babies. They were both uncomfortable with being handled and having laptime, and were afraid of the usual house-noises. A few things I do for them are -
- Use a cuddle cup/cosie when they’re on your lap and offer their fave foods while there inside. Being surrounded on three sides by the cosie provides comfort and the feeling of ‘hiding’
- Talk to them constantly while they’re out, maybe even try singing (my little boy Butter is very timid but he loves being sung to and he will sing along with me!)
- if they’re not in a cosie I usually have them against my chest, near my heart (heartbeats provide comfort to small animals) and create a ‘cave’ under my chin so they can burrow their head under there
- When they first arrived I sat and hand fed them their veggies a lot, it encourages them to associate you with food and eventually when humans approach the cage they will come out instead of running to hide. Had to make sure they each got a piece at the same time though!
- when they’re in the run I make it big enough so I can sit in with them. I don’t try and interact with them, just sit there and become a piggie play toy. It’s great until Mousse decides to ‘taste’ my feet

but it does help them build confidence around you. Just don’t move quickly!
Above all, perseverance. All piggies are different and will take to different things. Mousse loves laptime now, even when I brush him (check out the Floof Club House, he needs a lot of brushing

) and he especially likes watching telly. Butter is still getting used to it but he is now singing to me and eating when he’s out and he likes snuggles, he just hates loud noises or sudden movements. He has just started coming to me when I sit in the run as well (Mousse will clamber all over me, he’s not shy at all!).
