Most pet-proofing advice is overkill. A handful of changes covers the actual risks; the rest is up to your pet learning the house rules.
Actual hazards
- Toxic plants (lilies, sago palms, philodendrons) — relocate or rehome
- Loose cords and small swallowable items
- Open windows on upper floors, especially for cats
- Candles, essential-oil diffusers, and certain cleaners
What's usually fine
Furniture, rugs, and most decor are fine — your pet will learn what's theirs and what isn't with a bit of teaching.
If something keeps getting into trouble, the answer is usually managing access, not endless redirection.
