Now for cerberus, i'm not gonna lie as balance on this one was difficult and apparently still is. I'll do something in the next patch, probably had a cheat to render him easier. I personally recommend 2 columns of cats, 1 column of shields in front and the rest fire witches. Replace the shields as they expire, or you can even place cats in front, usually works too.
Good news is, you're only struggling to defeat the literal Gods!
