Rescuers from CHAT rushed to help after the woman alerted them, and they heard the heartbreaking meows of cats inside, too. But because the boxes had been left in an alley near a busy road in Stratford, rescuers had to be super careful.
"There were no air holes in the boxes," CHAT wrote. "We didn’t know their temperaments so didn’t dare open the boxes and risk them flying out into the road, so made a few tiny holes to let air in but not big enough to allow them to rip at the cardboard and escape."
A short drive back to the animal clinic later, rescuers were able to discover whose lives they had just saved.
