I familjen Weasley ser familjen ugglan Errol att bo i de gemensamma rummen. Han har en abborre i köket, nära bakdörren, men kan också hittas på en stol eller på tappbordet.
Från HP och hemlighetskammaren :
"Morning, all," said Percy briskly. "Lovely day."
He sat down in the only remaining chair but leapt up again almost immediately, pulling from underneath him a moulting, gray feather duster - at least, that was what Harry thought it was, until he saw that it was breathing.
"Errol!" said Ron, taking the limp owl from Percy and extracting a letter from under its wing. "Finally - he's got Hermione's answer. I wrote to her saying we were going to try and rescue you from the Dursleys."
He carried Errol to a perch just inside the back door and tried to stand him on it, but Errol flopped straight off again so Ron lay him on the draining board instead, muttering, "Pathetic."
När det gäller matning är @ThruGog förmodligen rätt: de matas delvis av sina ägare hemma och går ut för att jaga sig själva. I Errils fall kan han vara för svag för att kunna jaga mycket, så Weasleys ger honom förmodligen främst owlpellets.
