I didn't know about "the potential for the virus to enter animal shelters".

"The virus has evolved, and the way that it jumps between species—from birds to cats, and now between cows and cats, cats and humans—is very concerning," lead and senior author Kristen Coleman, PhD, said in a University of Maryland press release. "As summer approaches, we are anticipating cases on farms and in the wild to rise again."

Of particular concern, she said, is the potential for the virus to enter animal shelters, which could cause large outbreaks potentially involving people, similar to or worse than what happened in New York City in 2016 with a different avian flu strain.
