Haha yes, but it wasn't related to the cats.
The problems with the velcro were:
* The stitches that mated the velcro to the blackout material constituted little pinholes, so an additional layer was needed to patch those up.
* There's always a battle between the sticking force of the velcro and that of the tape that sticks the velcro to the window. The question is which one wins
* Velcro all around a sizeable piece of blackout material is pretty darn difficult to tear off - esp. without damaging either the tape (see above) or the curtain itself.
The net result was that during the years I used that room as a darkroom, the blackout curtains just remained in place. I could just as well have affixed them there permanently.
In my current darkroom I have removable rigid panels (which were surprisingly easy to make) which I just push into the window when needed. Far more convenient and effective!
