cat keeps peeing on my shoes

about 2 years ago we found this cat outside of our house. He was very tiny and we thought that he was a kitten. We took him to our vets and it turned out that he was actually about 8 years old and was abused and was starving to death. So we took him in and we noticed that some times he couldnt make it to the litter box on time and would leave us a "present" on the floor. After about 2 years of this we took him again to the vets because we were finding a little bit of blood in his stool. The vet told us that he has Corona Virus and that there wasnt anything really that he could do to treat it. He recommended that we switch his food which we have, but it really doesnt seem to be making that much of a difference. Last month my dad left to go out west to work and the cat seemed fine. he was a little extra affectionate because my he was alone through out the day with only our other cat (who could really care less about him) to keep him company. a couple of weeks ago we kept finding poop in our living room on the floor and furniture and also in my parents bedroom on the floor. Last thursday when i came home all of my shoes were covered in urine. it seems like he targeting me for some reason he keeps peeing on my shoes and im kinda at my wits end. i thought that it was because he was home by himself all day but this morning i found another puddle on my sandals and i have been home with him all day. My thought was to kennel him while we were gone during the day but im starting to think that that wouldnt really make a difference. Can someone please HELP ME!!!!!!!!!!!!!!!! i dont know what to do with him!!! I've put his face in it I've swatted him on the nose and NOTHING seems to be working!!!!!!!!!!!!!!!!!!!

I would start by getting him checked at the vets - some cats stop using the tray when they are ill.

Putting his face and/or swatting him on the nose may well make things worse - they certainly won't make them better.

And he is rather young for this if you have his age correct - it's hard to guess what age most adult cats are:

If a human pees on your shoes, that person is targeting you as someone they want to get back at. If a cat pees on your shoes, it has absolutely nothing to do with getting back at you or targeting you with something distasteful. My Raven used to pee and poop on furniture, rugs and clothing during times of stress, even very minor things. He had been a feral, then had been housed in a small space with multiple other FIV+ cats at a no-kill sanctuary that was more concerned with saving lives than quality of life. Your cat's abused past seems to have left him with the same sort of easily stressed personality.  Or, he is ill, perhaps both. A trip to the vet is the essential first step.

By rubbing his nose in his own waste or swatting him on the nose you are ramping up his stress levels and making things worse. You are using methods that a human child and perhaps a dog would understand, though I hope you wouldn't do this to a child or dog either, but a cat just won't get the relationship. He has no idea he has done something "wrong".
 

thank you for those links. im going to try a few of the suggestions. thanks again
 

You need to review all the ideas in the links and work through them.  Also think about if anything related to each one has changed.  But a vet trip is the first thing to do.
