Craig Williamson, from the garden centre, told BBC Scotland News that CCTV showed the otter coming in at about 12:30 on Monday, and having a “sniff and a wander”.
It then headed to the top corner of the premises – probably to sleep – concealed under a shelf until the following day.
“It then reappeared at six in the morning to have a wander and its breakfast with a munch on some dog food and bird seed,” he said.
“It was discovered when the shop was opened at nine o’clock.”
He said they did not initially realise what had caused the disarray in the premises.
