Any ideas how to stop cat peeing in the house?

Bit of a long story sorry. We've had our cat for 9 years, she was a rescue cat and is probably about 13 years old now. She was diagnosed with diabetes shortly after we had her and is on insulin injections. We've had a few ups and downs with her diabetes but generally she's been a healthy cat.

For the last few months she has been pooing fairly regularly in the house. Sometimes it's a whole stool, other times its a few bits or a smear on the sofa. Her back legs are a bit weak, and our vet thinks she may have some sensory problems and perhaps can't feel that she isn't clean if that makes sense. It sounds revolting but sometimes she comes in from the garden and there is poo hanging from her bottom so this theory does make sense. It has become quite an issue as we are constantly on poo-watch! The vet has been looking into dietary changes to see if that may help. There have also been a couple of new cats around and though she doesn't seem particularly bothered by them we did wonder whether this was contributing.

Now we are having problems with her peeing in the house as well! We've been having some building work done over the last couple of weeks. We had to move out because of the mess but left the cat here as we thought she would be happier in her own environment (in the past moving her out has upset her diabetes). It has been noisy work, but for the first week my husband was here all day, every day, so she saw a familiar face. And for the last few days of the job we were coming down twice a day to feed her and give her medication - and the work was much quieter by then anyway.

But she had pee'd in the house a couple of times before we returned - always in the same place - and has continued to do so since we returned. We've thoroughly cleaned the area, used a citrussy smelling cleaner, and put down things on the floor, including bubble wrap (thinking she might not like the feel) to try and stop her. But the problem continues. There are no other signs that she is unwell or her diabetes is unstable so I'm presuming its behavioural, perhaps in protest to the recent chaos! DH is ready to make her live permanently in the garden! But she's always been a house cat, and she's elderly so that feels a bit mean!

I will be speaking to our vet in the morning but any advice gratefully received in the meantime. Thanks
