Indeed, I see no issue with cat poo in gardens. Assuming it’s your own cat I’m not sure why you do either, the alternative is to train it to use a litter tray. Forcing it to use other people’s gardens isn’t exactly nice is it? If you don’t want it, no-one else will. That said, I don’t care about cat poo, especially as it’s usually in the soil which is helpful for the plants. I find dog poo in the middle of my grass more of a problem (and far more common!).
FWIW from experience, the more you try to put smells down to stop cats weeing and pooing in a certain area, the more you force them to do it (territory marking etc).
I can just about cope with the poo but the garden birds have stopped coming now
It’s winter, they stop coming so much over winter 🙂 But all jokes aside, we had 3 cats (2m, 1f) over 20 years (all 3 at the same time for abotu 10 years) and about 5 other local cats visiting, and a healthy garden bird population without regular killings, it’s unlikely to be linked.
