Hmmm, I'm on the fence here.
I have rehomed GP1 through to GP6 so I know there are homes out there, though there's no way of knowing how long a pig would wait.(Some stay as permenant residents)
But , TBH, unless there are allergies (and my DD is allergic to Rex and Teddy fur) then why not keep them? A Rescue will assess the new owners , unless you know the new owners personally, you won't know for sure.
Ok, they need a daily commitment,, but as the adult, you signed up for them.
When my DD doesn't want to go out to the Pighouse in the rain (I don't blame her) it was ME that signed those papers, I'm over 18 , she isn't. So it's my responsibility. DD is brilliant with them, but I know she's got school and social life.
My pigs have each other, food, space, a cuddle and chat every day,
They do live down the bottom of the garden (well halfway) in an ice-cream tub .
They pretend to be judgey when we cuddle them, it's taking them away from the food.
