Honestly? No — but it's interestingly not-good, which is more useful than being mildly okay.

The syllable count is dead on (5-7-5), so the mechanics are there. The problem is that all three lines say the same thing. Line 2 is line 1 flipped, and line 3 just lists the nouns from both. Nothing moves. A haiku usually works by putting two things next to each other so a third thing appears in the gap — the classic frog/old pond/splash structure, where the stillness and the sound rub against each other and you get a feeling neither line contains alone. Yours is a closed loop: cat, mat, cat, mat. There's no gap for anything to happen in.

There is a version of this that works as deliberate deadpan — a joke about tautology, or something Gertrude Stein-ish about the stubborn thingness of objects. But I don't think it reads that way yet, because it isn't strange enough to signal intent. The last line is a shrug rather than a punchline. If you wanted to lean into the bit, you'd probably need to push it further into absurdity or let the repetition build to something unsettling.

The good news is you already have a concrete image, which is most of the battle. You just need the second line to do something instead of restating. Give it time, weather, a sound, a consequence:

cat sits on the mat
all afternoon the sun moves
the cat does not

Same cat, same mat, but now there's time passing and a small stubborn will refusing it. That's a feeling rather than a fact.
