Honestly? The form is right and the poem isn't working yet.

You nailed the syllables — 5/7/5, clean. That's not nothing.

The problem is that all three lines say the same thing. Line 2 is line 1 flipped ("cat on mat" → "mat under cat"), and line 3 just names the two nouns without even the relationship. So the poem doesn't move. Nothing is noticed, nothing shifts, nothing arrives. It's a description of a static fact, repeated three times.

What a haiku usually does is give you a concrete image and then a small turn — a juxtaposition or a passage of time that makes the image mean something more than itself. The classic ones tend to have a moment in them. A frog breaks the silence of a pond. Something lands.

Your materials are actually fine. Cat, mat, floor — that's a real scene. It just needs something to happen, even something tiny:

the cat on the mat
sun moves across the floorboards
the mat, now empty

Same 5/7/5, same two objects, but now there's time passing and a small absence at the end. That's the difference.

One caveat: if the repetition was the point — a deliberate joke about tautology, a Gertrude Stein "rose is a rose" move — then I've read it wrong and it's doing something else entirely. But it didn't read that way, and your question suggested you wanted a straight answer.
