Happily, I can report that no animals are killed, hurt, or even distressed. You see a cat (the kitten from the first movie, now an adult named Lasagna), a dog (whose evil owner is killed, but who is adopted by the heroes) and a wolfdog (kept in a theme park attraction, but rescued before the end and adopted by the family). All are given a happy home and plenty of love and kindness from the protagonists.
A toy won at an arcade immediately has head ripped off by a bully. Child is later seen with the toy though so they either got a new one or it was repaired.
