Some dogs like to roam just like cats, we had one of those. Dog gone again, call the next farm, dog there? Nope, not this time. Explore the forest to find him a few kilometers off eating from a moose carcass, joy. Once home he vomits up half a moose which he wants to eat again. Yes that's dogs for you.

See, I am the only house owner in the street without a cat. Guess whose garden is very frequently visited by literally all the cats? Isn't there some plants to repel them? And no I'm not getting a dog

Go to your local gardener and ask for plants that repels cats/has scents cats don't like and plant them where you notice they use as a bathroom. Some people plant plants with thorns/prickles too, which seems to help a bit after the cats learn it hurts.

Most obvious solution otherwise is to have a fence if you don't have one already.

What kind of fence keeps out cats? They are pretty good climbers and jumpers.

A fence where the top part protrudes outwards towards the side of the invaders. Aka "anti-cat fence".
