After a couple of days consulting various authorities - among them the Mosgiel Volunteer Fire Brigade - an SPCA-contracted builder concluded the only way to get Jelly out was to make a hole in the wall.
The last she heard from the SPCA, Ms Bekkers said, a builder was coming on Friday night to drill a hole.
''And I said, I'm away from Friday night, I won't be here. So you can't be in my building ... My landlord wasn't happy with [a hole being drilled] without consent,'' she said.
Ms Bekkers' landlord declined to comment to the Otago Daily Times on the record.
Several hours after De Winkel closed on Friday night, an SPCA inspector went ahead with the rescue, search warrant in hand, accompanied by a locksmith, a police officer and a builder.
Although they entered without Ms Bekkers' or her landlord's explicit consent, the SPCA's actions were legal under the Animal Welfare Act.
Otago University Faculty of Law lecturer Marcelo Rodriguez Ferrere said the Act awarded certain rights to designated inspectors to assure the wellbeing of animals, including the right to obtain search warrants not unlike those that the police use.
Based on facts about the case provided by the Otago Daily Times, Mr Ferrere said he was ''confident that the measures that the SPCA took were likely to be within their legal powers''.
Also, Mr Ferrere said ''legally, the SPCA would not be obligated to fix the hole [that they had made]''.
But SPCA Otago spokeswoman Kirsty Thomson said the cost of the repairs definitely would not fall on Ms Bekkers or her landlord.
''We're not sure if we're fixing the hole or if the owners of the cat [Rod and Lynnn Galloway of Mosgiel] will be fixing the hole, but it will definitely be fixed by one of us,'' she said.
''Not at the tenant or owner's expense.''
Throughout the ordeal, Ms Bekkers said, she was ''surprised at how much power the SPCA has in accessing premises''.
But she emphasised that she was happy the cat was rescued.
''But ... I just feel a bit insecure that people can just come into my shop - or it could have been my house - without contacting me. It still feels wrong to me.''
Jelly, aged about 3 years old, was reported to be on antibiotics and painkillers but doing well.
