🌿 The Truth About Catnip

Catnip (Nepeta cataria) is a favorite for many feline friends 😺. It contains cis-trans-nepetalactone, a mild hallucinogen. Effects include rolling, rubbing, and general merriment—but it can also cause overstimulation or aggression in some cats. Avoid use in cats with seizure history or behavioral issues. Use catnip only as an occasional treat and never place it in travel carriers, as it may increase stress. 🧠

🌱 Tips for Pet-Safe Gardening in 2025

• Check every plant before you buy or plant 🌿
• Place toxic plants in fenced or elevated areas 🧱
• Use pet-friendly mulch and avoid cocoa shell mulch (toxic to dogs!) ❌
• Clean up mushrooms quickly—many wild types are lethal 🍄
• Install barriers to deter digging in sensitive zones 🐾

🐾 In Case of Ingestion: What To Do
