"It was raining quite heavily and he looked a bit cold and wet, huddling to take shelter in the covered area outside," Nyatsambo said.
Nyatsambo said she went to look up the phone number for the RSPCA to have rescuers pick up the feline, and when she returned to check if the cat was still there she found it had somehow crawled between the automatic doors and gotten stuck between the panes of glass.
RSPCA Animal Collection Officer Kate Wright responded to the scene.
"I'm not sure whether he was actually trapped or whether he was just trying to find someone safe to rest," Wright said. "He was soaking wet and freezing cold and had been trying to find somewhere warm and dry to curl up -- unfortunately he chose a rather hazardous spot!"
Wright carefully pulled the kitten out of its hiding spot and took it to a veterinarian, where it was dubbed "Lenny" by staff.
"It's not clear whether he's a stray or a lost pet and, unfortunately, he isn't microchipped so I've put up posters in the area to see if we can find an owner for him," Wright said. "He's a lovely cat and, thankfully, appears to be in fairly good health."
