Officials said a two-pound, eight-week-old kitten was dropped in a public mailbox in Boston and later found unharmed among envelopes and packages.

The kitten they're calling "Postina" likely was stuffed Friday through a small opening of the mailbox and dropped several feet below, according to the MSPCA Animal Care and Adoption Center.

A U.S. Postal Service letter carrier discovered Postina on Saturday during a scheduled afternoon pick-up.

The MSPCA is offering Postina for adoption after several days of nourishment and a round of vaccinations.

Animal abandonment in Massachusetts is punishable by up to a $2,500 fine and 5 years in prison.

The MSPCA said there has been a 48 percent increase in pet owners citing financial reasons for surrendering their pets.
