Nylon carpet and cat wee - more resistant than wool?

[EmMcK]

My mother is having her house repaired after earthquake damage and one of the things that she is considering doing is replacing her 40 year old carpet. Hooray!
Mum has a cat and a dog both of who sometimes wee on the floor. Nylon carpets don't sit right with me somehow, but I wondered if they would be a better option for mum given the pet wee.
Has anyone got an opinion on this fascinating question

Bump bump

Nylon carpets have rather fallen out of favour. They seem to flatten quickly and look worn out because the pile is floppy.

Polypropylene is a very durable carpet that stands up to vigorous cleaning (even bleach). I got some for a playroom and it seems OK.

Look for a "twist" which means the pile has been crimped to make it stand up better, and a "heather mix" which means it is mottled or speckled so that marks do not show.

It will still squash under furniture feet, but you can raise it again by hoovering.

The trouble with bleach on cat wee is that they smell it and think another cat has been - it can actually make the problem a lot worse.

However, polypropylene carpets are tough as old boots and will stand disinfecting, scrubbing, steaming, you name it.

It might be better to look at a fully wipeable, harder surface, though, particularly if your DM is getting on a bit.

If you drop anything hot on them they melt ..... iron marks on carpet is not a good look, and as for the static electricity and crunchy feel as you walk across it in any sort of nylon hosiery. Horrid.

The trouble with wipeable surfaces is that they are usually lethally slippy when wet which is more of an issue with an elderly person than the lingering whiff of pet... imo.

Personally, I'd buy a fairly inexpensive wool carpet and arrange for it to be professionally cleaned once a year? And get some pet nappies or indoor litter trays if elderly incontinent pets are an issue.

Thanks folks. Nylon does seem grim to me, and we are in NZ so it seems like heresy not to get wool. I am hoping that once the smells of 40 odd years of animal misdemeanours has gone, that they won't be so tempted to make the journey three foot outside.
Like the idea of an annual professional clean too.
Mum is 78 and is a little overwhelmed by all this forced change so thanks for helping me help her.

ive got four cats and the best thing i have bought is a £99 vax carpet cleaner perfect for getting small areas clean especially bits like a cats weed on an area, but i had pure wool carpet in my last house and it seemed to soak up dirt and hang on to it i could not get it properly clean no matter what i did
