Petnet Inc., a privately held Los Angeles company that sells automatic pet feeders for cats and dogs, has received a $3.75 million cash infusion, according to an SEC filing.

The 5-year-old downtown Los Angeles company said in the filing Wednesday that it had sold more than half of a planned $6.5 million equity placement to three investors.

Petnet, which produces digital Smartfeeders that allow owners to feed their pets from remote locations, was incubated in Boston.

It received a $1.1 million seed funding round three years ago after moving to Los Angeles, then two following rounds of $6.2 million and $15.6 million. It has operated since 2015 as a subsidiary of Aboitiz Equity Ventures Inc., based in the Philippines.

The firm generates an estimated $978,104 in annual revenue and employs 11 people, according to Buzzfile.com.
