Which agency would handle cases relating to animal welfare and control?

The agency that would handle cases relating to animal welfare and control is County Animal Control. This agency is specifically tasked with enforcing laws concerning animal welfare, such as responding to reports of animal cruelty, managing stray animals, and ensuring public safety in relation to domestic and wild animals. They typically have the authority to impound animals, investigate cruelty cases, and promote responsible pet ownership within the community.

While police departments like La Habra Police and Placentia Police may have officers trained to deal with animal-related incidents, their primary focus is on public safety and law enforcement within the community. The District Attorney would be responsible for prosecuting cases that come from law enforcement agencies but does not directly manage animal welfare issues. Thus, County Animal Control is the designated agency for these specific matters, making it the correct choice.
