Pets made $50,5 million on its second weekend of release which brings its total after 10 days of release to $203.1 million.
The film is looking very strong and with the American school holidays in full swing this could be the one to beat this summer season.
Paul Feigs Ghostbusters reboot couldn't quite make it to the top on its debut and fell into second place with $46 million including preview shows on Thursday night.
This isn't at all bad and would have topped had it not been for the strength of Pets, good reviews have helped and it should hang around for the summer season.
Also new this week is The Infiltrator at number 8 which debuts with $5.2 million.
Highest total grossing film in America on the top 10 is Finding Dory which is at number 4 this week with a gross of $445.5 million while the longest running film is shared with Dory and Central Intelligence.
