How can I repair wood trim ruined by cat urine?

Hello all. My cat peed (ugh) on the carpet and I sprayed it with cleanser and now the wood trim is all puffy. I have a fan on it as we speak but I am wondering if anything else can be done?

  • Hi, Sarah Catherine!

    A bit of sanding may help once it is dry... make sure to use small strips on any detail (curves, carvings, etc.) then apply a fresh coat of paint. Otherwise, if it is something that is truly noticeable, the piece may have to be replaced! I have cats and I totally understand... I hope this helps!

    Sadly our cat did the same thing. I ended up removing the trim. Scrubbing it and letting it dry flat in the sun, then sealing it and repainting got rid of the smell. That will give you the chance to clean the edge thoroughly, too, where it covers the edge of the carpet.

    After you fix it, get a spray bottle with water & every time the cat does something you do not like spray her. After a while she will not do it or if you make a sound like psh psh your prob should be solved. It worked for me for keeping cat off furniture & when a guest picked cat up to sit on their lap on couch cat jumped off. Great training tool& non toxic.

    If it swelled my guess is that the trim is made from MDF or medium density fiberboard. I had something similar happen to a table top that swelled when a watered houseplant got into the particle board under the veneer.


    If it's still bumpy once it's fully dry you can try using a very sharp box knife and gently shaving down the areas that are still bumpy. I'd then coat it with some primer first followed by the trim color.


    We've done a lot of diy in our house and I'm sure once it's painted no one will really notice it. If our visitors have noticed some oopsies that are still on the baseboard trim in our entryway they've never mentioned them to us
