In 1978 Oregon, Ben and Jules inherit an abandoned coastal property from Ben's late mother, who's never mentioned it. The untouched house has been kept a secret for 40 years and comes with a beautiful private cove and beach. Jules searches for answers while Ben unwittingly awakens a fiercely protective creature.
Watched the whole movie and saw no deceased cat thankfully. But a Raccoon is found deceased in the plumbing, so perhaps people are using the cat category to report that.
In the beginning an axolotl is found dead (or barely alive?) after being cannibalized by a tank mate. While no rat is killed, there is a brief moment where a rat goes missing and jokes are made about it getting eaten alive. There’s a dead fetal mystery animal shown later in the film as well.
