Can this be given orally?

Answer by Chewy • Apr 25, 2024
This can be given orally or put in your pet's food.

I've tried the Composure Mini Bite-Sized Dog Chew. Not effective for my Chihuahuas. Is the liquid a stronger dose? (Asking since it says MAX.)

Answer by Chewy • Jun 01, 2019
The liquid VetriScience formula per ½ teaspoon contains 134 milligrams of Thiamine, 22 milligrams of C3, and 21 milligrams of L-Theanine. The VetriScience Mini Bite-Size formula per chew contains 67 milligrams of Thiamine, 11 milligrams of C3, and 10.5 milligrams of L-Theanine.

How long does the effects last? ( 11lb old kitty who pees next to litter box and hates dogs and a 35lb year old dog rescue who loves the kitty and has anxiety issues)

Would not eat

My cat would not eat this and I mixed it in his favorite fussy cat linkable treats also tried in wet food. No luck. Basically, waste of money for us

Cats won't eat it

I had hoped that this would help reduce the anxiety of my two indoor cats. They both are very easily spooked - afraid of the doorbell, vacuums, new people, etc...Unfortunately

Calming

I love that this has l-theanine in it. The fact that it can be used for both csts and dogs is a bonus and the liquid mixes in easily with both wet or dry food.
