We live in a fairly built-up area, but large gardens. I suppose classed as "Suburbia".
Most of our neighbours have cats. Someone further back said that if there are cats, there is no other wildlife.
I disagree - we have foxes, hedgehogs, squirrels, rabbits and an enormous variety of birds.
Another poster said her chickens were attacked by a cat. NDN has chickens, who wander into our garden from time to time. One of our cats tried once to attack it and was made to retreat, quite definitely. She never tried again!
We sometimes have neighbour's dogs wander into our garden (we don't have fences, just hedging and bushes). We just send them back again. Dog poo and fox poo are far more offensive than cat poo.
NDN's chickens sometimes come into our garden, quite happily.
We have grown vegetables for as long as we have lived in this house - about 25 yrs. We have never had a problem with cat poo spoiling it. We own cats, most of our neighbours own cats.
We all have large lawns. I have never found cat poo on a lawn, neither have my neighbours. Not saying it doesn't happen, but none of us has ever experienced it. It is more likely to be fox poo (which really does stink)
We all have grown children (and some now have grandchildren). No-one has contracted toxoplasmosis from a cat (or it's poo (perhaps we have been more vigilant about washing our hands . . . ?
I think some of these little anti-cat scenarios are made up.
To finish - someone said above that humans are more important than animals and accused other posters of 'anthropomorphising animals' . Firstly, I don't think anyone has tried to humanise their pet. And whilst I might agree on one level for the first point of humans being more important initially , it is not quite as clear cut, as humans need animals to live, believe it or not. We all do need to live together, harmoniously.
Human live could not exist without animals, and I'm pretty sure David Attenborough, Steve Backshall and Co would not agree with your point there. (can't remember which poster said this, maybe Mythical?)
