Our read

An exact tie: these two NASC-sealed calming chews post identical scores on every dimension, and both are built on L-theanine with the same modest evidence. In our view the tiebreak is cost, where Pet Naturals runs cheaper per day, though both land in the same value band. The rubric does not separate them.

This verdict is our opinion under the PetScored rubric, not veterinary advice. The exact sub-scores are in the table below; each product’s source confidence and limitations stay on its own scorecard.

Pet Naturals

Calming for Dogs and Cats

The studied L-theanine form, fully disclosed and very cheap per day, but at 5 mg it is well under the studied dose; weak evidence and a low dose hold it to Mixed.

Partially verifiedDogs & cats

VetriScience

Composure Calming Chews

A calming chew scored on its disclosed L-theanine (the studied Suntheanine form); the C3 colostrum complex is not in our evidence library and at 21 mg the L-theanine is below the studied dose, so it lands Mixed.

Comparison scores use the same reconstructed score-event math as the supplement scorecards. Source confidence, unresolved gaps, evidence-library citations, and dose caveats remain attached to each individual scorecard.
