I mean, if you're concerned about the cat's health, keeping it indoors (or in a cat patio) is probably going to reduce the risks to the cats health way more than skipping a collar will, and you won't need a collar.

Physically yes, mentally I would argue not so much.

I'm not sure being terrorised by dogs is particularly good for a cats mental health either.

In some cases it is the opposite...but I guess you think you should be put under house arrest for your mental health too. There are so many dangers outside.
