I used to use steel screen but these days I prefer fiberglass. Less toe catches when the paw actually has to hit to pan

I too like the black weed barrier cloth it does a great job and will even let water through the fabric but it only lets water through from one side not both I think the shinier side goes down and water will go through it but if its up the water will not drain through it or vice versa I cant remember off hand. I use wax paper and the weed barrier both and like both. wax paper is super cheap and I just cut the roll into 3 rolls it lasts a long time. I think one roll of weed barrier would last a lifetime if only used for pan covers and the stuff is cheap as well.

are you looking for steel screen to increase the pan surface?

My cat season isn't open yet. Those we're both coyote sets that cats found. We only have a 10 day season for 1 cat because they say we don't have many. Lol
