Giant cat-dinosaur hybrid.

A giant cat the size of a house with body features of a dinosaur. Either scales, an extra set of arms, a bigger snout, or spikes coming out of it's back.

I legit had a dream about getting sucked into an alternate dimension awhile back that had these creatures in them. They would hunt humans for food and take over their houses to use as their boxes (like you know how real cats like boxes). The humans were struggling for survival against these beasts. When they were ready to hunt, they would utter this big shrieking MEEEOOOOWWW which signaled that the humans need to GTFO lol
