From Chicago ... and with more than a thousand solves on that puzzle we've never received a single complaint about the rhyme on that one (plus the stats say users find it an extremely easy rhyme to solve)! Curious how you pronounce that one such that they don't rhyme?
According to the dictionary (and matching my own non-native pronunciation), cactus is /ˈkæktʌs/, practice is /ˈpɹæktɪs/
The terminal /tʌs/ is not quite the same thing as /tɪs/; since they are both unstressed, the difference can be hard to notice in fast speech, but becomes clear when enunciating.
