I saw several people direct you to the ASPCA website, but here are some from personal experience with:
All Hoya varieties
All peperomia varieties
All pilea varieties
True ferns - be careful, there are some ferns (like the asparagus fern) that actually aren’t ferns at all. They’re lilies, and lilies are definitely not safe for cats.
Palms - majesty palm, ponytail palm and parlor palm are safe for pets. They are the most common palm varieties you’ll find inside. There are a few palm varieties to watch out for. In particular, the sago palm is extremely toxic to humans and animals alike. Best avoid that one.
All prayer plant varieties - this includes stromanthe, calathea, ctenanthe, and maranta
Spider plants - though these are said to have similar effects to catnip, they’re completely safe for occasional chewers
hope this helps! Anything to keep our babies (cats and plants) safe is worth researching
