Cute.
I found some words for you hehehe
Amulet
Beamlet
circlet
eyelet
toilet
I had help. I used litscape.com hehe It found 128 words that end in -let.
You can also go with non-conventional rhyming...
Parapet
bucket
let
met
Boba Fett
Who knows, maybe that last one would get a reaction from her.
Oh I could have used 'beamlet', she is a little one of those for sure! 'Toilet' would have been good, but is actually an issue with this cat, so it probably wouldn't have been appropriate in her head, even with the quality rhyme it creates. The food that I whipped out meant that I had finished her poem early, and she was fine with it.
Ah then, all is well :)
