No rodents are safe in New York City under Mayor Adams’ watch.

The rat-hating Democrat plans to sign a bill banning the sale of guinea pigs in the boroughs after city lawmakers approved the measure last week.

The pet peeve comes a month after Adams appointed a new well-paid rat czar to try to eradicate the vermin from New York.

Councilmembers approved the guinea pig ban after some 600 of the pets were surrendered to overburdened city animal shelters last year, according to December testimony from Alexandra Silver, Director of the Mayor’s Office of Animal Welfare.

Guinea pigs live for up to ten years, and there are a “very limited number of veterinarians” in the city that know how to neuter and spay them, Silver said.

“This common-sense legislation protects the wellbeing of guinea pigs and can also help lessen the burden on our animal shelters,” a spokesperson from the mayor’s office told The Post Tuesday.

“New Yorkers interested in welcoming a guinea pig into their home can do so by adopting from a shelter or rescue organization that can offer guidance and support in addition to a companion animal.”

Adams’ “hatred” of rats has been lampooned on “Saturday Night Live,” and Hizzoner will be portrayed as “Ratman” during this year’s upcoming Inner Circle production — an annual musical where city journalists spoof current events.

A judge ordered Adams to pay a $300 fine earlier this year in connection with a rat infestation at his Brooklyn home.
