Life Saver!!!

One of our cats had become so aggressive with humans and other pets we were considering giving her up for adoption. We had tried everything - pheromones, cannabis treats, nothing worked. Then we discovered Zylkene! The improvement has been amazing! She's like a different cat - friendly and playful. THANK YOU!!!

My poor Tomcat who was a rescue animal that I took in and cared for had some trouble adjusting to our new residence and disappeared for several days in March . He managed to pull off his tracking collar , so I left his favorite food by our door in hopes he would get hungry and return home. 7 days later he finally showed up but had awful wounds on his back, shoulder, and chest that required a vet's expertise. Buddy needed his head and torso shaved and treated with wound dressing and antibiotics for a month which meant he was housebound for the first time in his young life. I had no idea how he would react, and unfortunately it was very stressful on everyone involved because he just couldn't cope with being cooped up at night after the antibiotics began to work but also agitated him and he began to tear up my bilnds and scratch at the door like a wild beast. The vet suggested Xylkene in his food to help calm him down and I noticed the difference almost immediately. We work out a system to safely keep him in our garage at night so we could go back to sleeping at night until he was free of his infection and strong enough to get back outside with supervision. I now keep a supply on hand in case he gets hurt or sick and needs another trip to the vet, because he definitely doesn't like riding in the car. Thanks for this great and natural remedy for my poor kitty and for our solution for some sleepless nights. Buddy is back to his charming self and good as new 🐱

Great product for cat's anxiety

I have a 7 pound cat that was experiencing anxiety after I went back to work. She's a beautiful long hair cat who began over-grooming so badly that there were hair chuncks all over the house and she suddenly went from looking like a floofy puff ball to a thin shadow of what she was. The vet recommended those pheromones that you plug into the outlet. They had no effect. Then I found this suppliment. She's been taking it for 2 months now and she's becoming much closer to her previous floof ball self. I talk one capsule, open it up and mix into a small amout of wet food. She loves it as a treat and I'm so happy that her anxiety is so much better. I definitely recommend this product.
