1990, the group released a six-track EP entitled, Tingles, which was produced by Nick Mainsbridge (Tall Tales and True, Martha's Vineyard). McFarlane noticed that "almost immediately the frisky "That Ain't Bad" scored mainstream radio support." That track, combined with their cartoon, tattoo-ish artwork (which featured heavily on their releases and in their videos), saw Tingles reach No. 1 on ARIA Alternative Singles Chart and, in May 1991, the EP was a number-one hit on the ARIA Singles Chart for two weeks. "That Ain't Bad", the lead track, was Day's "simple attempt to mix noisy guitars and the words 'I love you' together in a song without one contradicting the other." The Canberra Times reviewer opined that it "has had the airplay, but it is not the best track. "Don't Go in the Water", a dire little track, and "Getting Away (From This World)", with its hackneyed but fairly successful insertion of sound from the Challenger shuttle disaster, are both excellent tracks." According to an Australian Musician Magazine staff writer, Ratcat were the first alternative band to go mainstream – they provided one of the Top 50 Most Significant Moments in Australian Pop/Rock History. The band's second album, Blind Love was released in May 1991, and its lead single "Don't Go Now" (April) both reached No. 1 on their respective ARIA charts. The song was co-written by Day and Robyn St. Clare (of the Hummingbirds). For recording, at Paradise Studios, Day, Polin and Zaid were joined by St. Clare and Margaret Urlich on backing vocals; they were produced by Mainsbridge, again. Zaid told Charles Miranda of The Canberra Times that their chart success was "really weird it happened so quickly it's sort of difficult for us to understand what has happened. And it does put pressure on us to come up with the goods. We have to look at what we've done [... but not] perform to any sort of dictated standard by what we've achieved." The group supported fellow Australian group, INXS, on the latter's Australian tour in April and May 1991 and followed by headlining their own Invasion of the Dinosaur Killers Tour in June. Their next single, "Baby Baby", was released in July and reached No. 21. In September they started a four-month tour across the United Kingdom, continental Europe and the United States. Polin described how "We were playing to full houses a lot of the way
