My 3yo son just ran across my front lawn and jumped in the car. On the way, he's trodden in cat poo ( there's a regular offender, and no, it's not fox ). There's now cat poo all across the back seat of my car. I'm first trimester, and horrified at the prospect of toxoplasma, even though I know the risk is low.
This is on the background of my aracuana chicks being stolen by cats from my own back yard. I don't care how lazy you think your cat is - research has shown that even the most placid cat will kill 2-3 animals per night if allowed to roam.
Keep them locked up ffs! If you can't keep them inside, make a run. If you can't do that, keep rabbits instead.
