It was released as digital download in the United States on February 17, 2015, originally intended as the first single from Free TC but was later scrapped.

The song garnered positive reviews from music critics, who complimented its club and crossover appeal, as well as XCX and Tinashe's vocal delivery.

[2] In January 2015, Sign confirmed that he had collaborated with Charli XCX and Tinashe on his upcoming studio album, Free TC (2015).

[8][11][12] The Source wrote, "There's $ign's signature sleaze, XCX’s Top 40, pep rally hook voice, and Tinashe's sexy steez".

[16] The track's lyrics discuss a scenario of meeting someone attractive in a club and communicating basest desires to them, while extolling the virtues of physical flexibility.

[18] Ian Servantes of Complex noted that "Drop That Kitty" was "highly sexualized" and fitting for clubs of both the stripping and non-stripping variety.

[19] Paper felt "Drop That Kitty" was "infectious" and an "undeniable jam," and praised XCX's chant and Tinashe's "soulful" crooning.

In his review of the song, Stern went on to opine, "'Kitty' isn't something any of them would likely drop solo: It's a combined effort of feisty pop hooks, cool crooning and hip-hop heat all in one go".

[14] Conversely, Music Times writer Ryan Middleton felt that Sign "[brought] it home" with the track's main verses.

However, Locket said that the song was "so bad" that it is "almost...good" and commented, "It's like the semi-G-rated-strip-club anthem you never asked for, and we can't stop dancing".

Rettig went on to comment, " With all of the talent that's involved on the track, it sucks that they didn't use it for something more substantial than a thinly veiled euphemism and a weak hook".
