Sorry to hear about this. I had pets growing up, and miss having one nonw, but between the high-dollar speakers and spousee's furniture, pets aren't happening for us.
After the original assault and different sprays or organic compounds have hit the cone, I would doubt that the TS properties of the driver will be unchanged. So ultimately, replacement may be in the cards.
To avoid a repeat performance, podiums, end tables, or other risers could be used to get the speakers out of the line of fire.
