If your talking about zoophilia/bestiality, you should know that the majority of furries condemn that behavior. I do too as it is animal cruelty.
Most furries aren't attracted to animals. Most are even into the sexual side of the fandom, nevermind interested in doing it with their pets! Those who are into the sexual side, it is more often than not isolated to anthropomorphic animals, in which case, they'd be able to consent in reality as they'd essential have the mental capabilities of humans. Zoophiles, like the controversial and big name "Hypnotist Sappho," who has been covered on YouTube by many commentary channels have been cast out by the vast majority of the fandom for what they've said and believe in.
If a furry is sexually attracted to an anthropomorphic animal, I say "so what?" If a furry is sexually attracted to an actual animal, then I urge them to get help because that's not ok.
Now please, calm down, stop being judgmental, and please try not to listen to stereotypes.
For farther information, I'll direct you to Anthony Padilla's YouTube video where they interview a few furries to farther understand them and to give the internet first hand information.
