My father is 95 makes every effort to make it to the toilet but stands and misses it every time. Any ideas?

Problem might be a white toilet seat, white bowl and maybe a light colored floor....
Try emptying the toilet as much as possible, (pour a bucket of water down the toilet and it will drain most of the water) Next dry an area at the back, bottom of the bowl and use a sharpie marker and make a big X in Red or Black, he should be able to see that clearly. Flush the toilet and the water will come back to normal. See if having a target to aim for helps.
Sitting down might also work but a lot of men are resistant to that.

If it is a matter of aim there's this:

This seems to be a pretty common issue... But it isn’t fun to deal with! My husband’s kidneys failed, so he has the opposite problem: no urine output. It comes with its own challenges.

If you search the forum, you should find some ideas. It might be a visual problem. I have heard suggestions of making the toilet bowl more visible by painting the seat or installing lights inside the bowl. (They sell lights for this purpose.) I’m surprised that the urinal didn’t help. You might try another type of urinal, like one with soft edges and a hose that can collect the urine or deposit it in the toilet.

Good luck. Hope you find something that works. It’s awesome that he still makes it to the bathroom at 95.
