WESTBROOK, Maine (AP) — The Animal Rescue League in Westbrook, Maine, won’t have to worry about how to feed the cats in its shelter for a couple weeks.

On Friday, an 18-wheeler pulled up and dropped off 87 cases containing 1,044 cans of cat food. The gift worth $1,000 was due to a miscommunication.

The truck driver delivered a load to Hannaford Bros. Co. in Scarborough but the supermarket chain had not ordered the cat food. The driver contacted Portland’s animal control officer who put him in contact with league. The driver said his boss wanted the truck back empty.

The league said the food is a big help since the shelter has been at capacity for several weeks with about 150 animals.

As for the truck driver, the league did not take down his name or other information.
