cats and speakers - looking for clues

In 60 years of audio I have had only two incidents: A pair of Proac Response 2's had the foam woofer surrounds shredded. And fairly recently they pulled down an acoustic panel that was leaning against the wall. it hit the connectors on one of my Maggies and tore it up. Not too bad for 60+ years of cats and audio. 

I used to own Definitive Technology speakers that had a wrap around cloth grill that could not be removed. I eventually bought two pieces of heavy vinyl which I then sewed Velcro to on the ends of the pieces. This allowed me to wrap the  vinyl around the entire speaker and easily remove them when listening to music. I used black vinyl to match the same color as the speaker. It completely protected my speakers, and the cats lost interest in scratching them when the covers were removed for short periods.

My previous cat was speakers-agnostic. When he passed away, we got a beautiful pure breed main coon kitten - a little angel. Very soon have discovered that my Sonus Faber Cremonas started to sound weird. After removing string grilles I was up to $10K surprise - the little angel has destroyed surrounds on all 4 woofers and scratched the leather front...I have ordered and replaced the woofers and sold the speakers with the full disclose of the damage done. 

For the next pair (Guarneris) my wife made covers from moving blankets and we have NEVER leave the speakers uncovered while not listening.

Still love the purring angel:-)

The "grills" protecting my Harbeth 40.2 anniversary speakers are wire shelves made for closets. There is a factory 90 degree bend on one side and the opposite side I had a sheet metal shop make another 90 degree bend. They sort of wrap around the speaker. I have an elastic band around the back to keep them in place.

Sorry, I had a nice picture that was in the post but it disappeared...
