You can put a bell around their neck, which apparently reduces their catch by half[1]. The cats usually don't look happy about it though.
Single point anecdata, but I once found a cat with a collar that remained stuck in a fence, the cat - attempting to get it off - managed to insert a leg inside the collar and that - with more attempts to get free - made a really deep cut under the armpit, the poor cat was half choked and it took weeks for the wound to heal. .
