"I felt guilty about it, to be honest. We weren't even aware that he was getting out. We were surprised to find that he was leaving the property, because on the occasion that he'd come outside of the house, he was afraid to leave our sight," says Skinner.
"He was meant to be an indoor cat with no intention of ever having him leave the property, so it was a bit of a shock to find that he was not only getting out, but he was bringing home someone else's toys."
Eventually, the Skinners discovered that Mufasa had been escaping through a bathroom window, which meant that he had to pass the family's two big dogs outside, who he was normally terrified of. Now, says Skinner, all the exits have been secured.
"He's definitely under house arrest now," she says.
