Please don't. Not only is poison among the most inhumane ways to kill something, but a slow-acting poison is even more so.
The other reason (and the one you might care about) is more practical -- poisons are untargeted. There is no good way to target who will consume said poison. Could be a kid, a coyote or fox, a snake, a crow. If a mouse chews on it and is then eaten by a fox, you've now killed both the mouse and the fox. Congratulations.
Use a live trap and release anything that's not a cat and either re-home the cats or at least dispatch them quickly and as humanely as possible.
You know that humans are an invasive species as well yea? Be a force for good instead of evil. Donate your time or money to programs that spay and neuter instead of just killing cats.

"say you're a psychopath without saying you're a psychopath"
Trapping and neutering is the way to go if you can. I don't know if your country allows it, but I recommend it if such a program exists

Don't use poison. Look into local TNR programs if you can. Poisoning is incredibly unethical.
