Feliway Classic Calming Diffuser Refill
Feliway Classic Calming Diffuser Refill uses a synthetic feline facial pheromone to modify the environment rather than the cat’s chemistry, making it a top choice for household issues like urine marking and inter-cat tension. Its technical advantage is continuous, passive delivery via a plug-in diffuser which can be more cost-effective over time for multi-room or long-term use compared with daily oral supplements. Unlike ingestible options such as Zylkene or VetriScience Composure, Feliway avoids systemic exposure and pairs well with oral products or Rescue Remedy for event-specific situations.

Review Summary
"Widely regarded as effective for reducing urine marking, scratching and situational stress when used continuously; many users see clear improvement but results vary and ongoing refills are expensive. Best for multi-cat households or chronic stress rather than one-off events."

Zylkene 75mg Capsules
Zylkene 75mg Capsules are a single-ingredient, milk-derived calming peptide that offers predictable, veterinarian-friendly oral dosing for situational or short-term anxiety in cats. Their technical advantage is a targeted, systemic mechanism that can be administered around specific stressors (travel, vet visits), and because they’re a single active ingredient they are often easier to evaluate clinically and mix with other treatments. Financially they sit mid-range—typically cheaper than prescription drugs but pricier than mass-market chews—making them a practical bridge between environmental tools like Feliway and daily supplement chews.

Pet Naturals Calming Chews for Cats
Pet Naturals Calming Chews for Cats deliver a palatable, chewable blend of calming nutrients designed for everyday use, winning favor for owner-friendly administration and wide retail availability.

Bach Rescue Remedy Pet
Bach Rescue Remedy Pet is a flower essence-based option prized for its safety profile and immediacy for acute stressors (storms, fireworks) without adding systemic pharmacology. Its key advantage is low cost and flexible liquid or spray dosing that can be layered with pheromone diffusers or oral supplements without known drug interactions, appealing to owners seeking a non-pharmaceutical adjunct. While it lacks the targeted biochemical action of products like Zylkene or VetriScience, Rescue Remedy’s gentle profile and low price make it a useful tool in a multimodal calming plan.

VetriScience Composure Feline Bite-Sized Chews
VetriScience Composure Feline Bite-Sized Chews combine a proprietary colostrum calming complex with amino acids and vitamins, positioning them as a veterinary-grade, multi-mechanism daily supplement for behavior support. Their technical advantage is a clinically oriented, multi-ingredient formula that often shows stronger study support than basic OTC chews, though that clinical positioning typically comes with a higher price point. For cat owners seeking a more robust, research-backed daily supplement, Composure is a stronger alternative to budget chews like Pet Naturals and complements environmental measures such as Feliway.
