No zoo board without scat thread. I'm not complaining.
8Chan's /zooscat used to have some fun threads and discussions. Wish it were still around because I've recorded some content myself by now, an active community for sharing it would be a godsend.
Personally I'm less into chewing or eating, though sucking on some certainly is enjoyable when playing with it. Fucking a huge pile of dog or horse shit on the other hand makes me cum so hard it's insane.
Dogshit is likely my favorite for this purpose because its softer consistency and different textures, especially when using shit from multiple dogs, grabs onto your dick perfectly. Not to mention it retains heat well, so warming it up in plastic bags with a hot water bath is a viable option should you not have access to any right from the source. For the purpose of fucking it thoroughly I recommend a tall glass or cup. If you only want to use it as lube, a fleshlight will work just as well. Of course there's also the option of collecting so much you have a literal pile, in that case simply go wild on it in your bathtub or shower.
Horse shit is a lot more aggressive on your dick due to it mostly being partially digested grass, but I highly urge anyone who hasn't tried it yet to go to your nearest pasture coming weekend, grab some fresh horse apples, keep them in a ziploc bag and fuck those fat horse turds whenever you feel like it. All weekend. Nut right in there. There's hardly anything capable of retaining moisture the way horse shit does. Hell, even piss into it if you like. All that cum and constant fucking will soften it up considerably, you won't be able to put that thing down.
