Thx folks. Mit does appear to be cast iron, and I didnt realize it was a functional sewer vent. The opening is wide enough for creatures. i understand bats can fly down. Interesting I just got those metal gutter guards on last weekend. Thats sounds easy enough with what kind of adherence- zip tie? Otherwise I could use screen mesh with a tie. i just feel better having it covered. If something came in where would it go?

I haven't heard of animals crawling down the vent pipe, but if you are concerned, you can get one of those round light-bulb-shaped screens for gutters and stick it in (after opening it up enough to not fall in, of course). I did that for a replacement vent on the side of one of my buildings where I thought a bird might nest on it.
