This looks to me like changes in how to decide which category to record an intake. Although, perhaps, the post 2008 change could be the result of the mandatory s/n ban resulted in people abandoning unweaned kittens instead of relinquishing them when weaned.
The rise in intake started before the law, but it doesn’t look like the law had much effect. Always keeping in mind that, with such a large intake, it takes a lot to make noticable change.
This is just a quick peak, not an extensive analysis. Since the law only affects the city, I’m only looking at the city’s Animal Services. I want to look at County animal control and the rest of the county.
