Using the legal definition of "abuse", yes it was illegal to sexually abuse animals. Their actions didn't qualify. That's what warrants clarification here.
I appreciate your definition of abuse here but it's confusing in a discussion about legality.
No, it wasn't. The laws are quite explicit about what "abuse" means, and if you take a gander at most laws (including Washington state's circa 2000 or so) in the context of animals it usually explicitly refers to physical harm (for example, mutilation) or improper living conditions. Charging them under Washington's existing abuse laws would've required the animal to be physically injured, which it wasn't. It's quite literally why they had to pass a new law.
I don't know why I have to explain this, but:
1) Sexual abuse can occur without physical harm or injury.
