I guess people in my area are pretty wise in terms of neutering and spaying dogs and cats. I didn’t see an intact dog, stray or being walked, until I traveled out of the northeastern US.
In Europe, we have a mix. In Germany and Austria, absolute majority of non-pedigree dogs is neutered/spayed, don´t know about percentage among cats. In Norway, neutering/spaying of dogs and cats is illegal. In my country, we have people from both camps (pro / contra routine castrations), however most shelters do spay/neuter now and some towns run catch-spay-release program for feral cats.
One phenomenon of this strange covid19 year is disruption of transport of tens of thousand stray dogs for adoption from stray-dogs-heavy countries (Romania, Ukraine, Greece, Spain etc.) to richer european countries that have no/negligent strays thanks to widespread spay/neuter policy. Closed borders and decreased air travel make it hard/impossible. The resulting pressure on local shelters and municipalities might lead to significant uptake of spay/neuter in these locations. If you can´t no longer export your problem abroad, you will need to solve it at source. Silver lining.
