I'd love to see some pics of your collection.  
Btw, I saw on Ebay there's a Hemingray Amber Lowex Insulator for sale for under 10 bucks.  The link's about a mile long or I'd paste it here, lol.  Found it through Google.  
These insulators are beautiful objects.  I remember when I was 9yrs. old I tried to get one off a pole by the railroad tracks.  Gashed my thumb while climbing the pole and never made it to the top luckily!
Well, anyway I'm glad you didn't execute the cats! ;)  How bout some pics of them too?  :)
