Calmer Cats, Less Agression

a year ago
I added a 3rd cat (not kitten) to my home. Despite slow introductions and pheromones running 24/7 throughout the house tensions and agressions were high. At my vets suggestion I began adding Zylkene to their wet food each night. It has made a big difference. Cats are much calmer, they don't love each other, but the agression is minor.

Yes, I recommend this product.

It doesn’t work at all on my 10 pound Min Pin. She has been taking the pill for 3 weeks and I see no difference in her disposition.

No, I do not recommend this product.
