"When I put on digital they would leave the room. "
Cat's and dogs can both hear higher frequencies than humans I believe so a cat or dog not digging the sound is probably a good sign something is not right at higher frequencies that might be subtle or not noticeable to human.
My dog is afraid of loud noises like thunder etc. If I played a well recorded thunderstorm sound effect through my system he would not like it.
He likes most soothing types of music though and I can trick him playing animal noise sound effects, etc. 9all digital) if I try.
If it sound good to both people and pets then there is likely good karma all around.
