Health monitoring while on fleece?

[MWpiggies]

Hello everyone! I hope you are all having a great day!
I was looking into making some fleece liners with Uhaul and fabric and wanted to know if I would still be able to watch for health problems (blood or discharge) without puppy pads underneath? Eddie currently has fleece on top of puppy pads and I can always look at the puppy pads when I clean his cage and see the colour of his urine. If I switch to just fleece, will I still be able to see his urine/pink or red stains and know if something is wrong? I want to be on the lookout for any pink or bloody pee as he has a sensitive bladder.
Sorry if it's a silly/obvious question, I'm just very inexperienced when it comes to fleece.
Thanks!

I suppose it would depend on the colour of the fleece, but it would be hard to see blood or discharge on most darker colours and patterns I think.
Would it be possible to make some white fleece pads to put in his usual pee spots to make it easier to check?

Yes, I could try that, thank you! Also, how would I get the pee stains out of that fleece?

We use fleeces and use distilled white vinegar to wash them. It takes out all stains and smells
