My kitty is a former feral who decided to become a house cat. After the first few weeks happily settling in, he began to develop extremely hyperactive and disruptive habits - constant roaming, vocalizing, breaking into cabinets & drawers, food obsession, and just could never settle. Even the slightest noise would wake him from a nap and he’d come running to investigate. His nervous system was so hyperactive after moving out of survival mode and into the chill, quiet house cat life. I saw results after the first chew. Now over a week in (with 2 chews per day), he’s a completely different cat. Quiet, calm, purring, and finally enjoying long naps. No longer phased by typical household noises, and his rather raccoon-like habits of ransacking the kitchen and constantly seeking food has significantly diminished. His calmness has also allowed him to bond so much more closely with my other kitty - they now cuddle, groom each other, play together, and sleep together. Like others, the edibility of the chew is questionable on its own. With how food motivated he is, he did gobble it down for the first few days without issue. But he soon lost interest. This really isn’t an issue for us, because it’s easy to crumble the chew and mix it into his wet food at meal times. I’m not yet sure if this will be a longterm supplement for him or only a supportive aid for a few months while his nervous system continues calibrating into the chill kitty lifestyle. Either way, I’m so glad I researched these ingredients and trusted the process. He’s so much happier, and so am I. 😻 Review: Al mio gatto non ha fatto granche' - ...piu' che altro perché dopo 2 giorni di assunzione gli ha dato problemi intestinali e ho dovuto sospenderlo. Ma il mio gatto e' sensibile di suo ai cibi, quindi di sicuro per altri gatti andra' bene. Posso dire che dopo mezz'ora dalla somministrazione dormiva che era una meraviglia, anche se il problema per cui lo ho acquistato era di smorzare la tensione che lui ha nei confronti dell'altro gatto di casa….lo aggredisce spesso per gelosia...un vero peccato che non abbia avuto la possibilità di testare bene il prodotto. Spedizione perfetta come sempre.

Very diffucult to give to my cat liquid fluoxitine with a syringe.** A: I had this problem.It’s a big deal! One of my cars was peeing on rugs, shoes, the dog beds.. I was losing my mind! I was desperate! I tried everything! I tried everything until I found what worked! Natures miracle calming spray & dr.Elsie’s herbal cat litter additive. The spray calmed him of whatever was stressing him out(maybe the cats outside?) I sprayed it everywhere! On the entryway, the doir mats, the dog beds, the furniture, the shoes, everywhere! and dr.Elsie’s herbal flakes got sprinkled on the cat litter to attract him back to the litter box.. we also changed the litter to dr.Elsie’s . And we have a happy house & cat now. I slowly decreased spraying natures miracle over a 2 week period. Continued with the rest. Hope this helps! **Q: Will this help with giving baths, I have a resuce that needs one bad and doesn't even like being held much less near water but is getting sores** A: These aren't any kind of sedative - if you're talking about semi-feral, you should go to a vet and just pay them to do it. I am not joking, that cat will rip your face off. It's a one time cost, well worth it and hopefully, they'll be able to tell you why he/she's getting sores. Traditionally, cats don't get sores from not taking baths, so I wouldn't expect attempting it would do any good. Try those 'cat wipes' - it's like a wet wipe that's safe for cats. BTW - These did absolutely nothing for my cat. They did not alter her behavior in any way, but she did think they were tasty. I tried them on more than one occasion, but zero results. Best of luck to you and keep up the rescue! :) **Q: My cat gets very angry and scared when my (recently adopted) dog comes near her. Would these help her stay calm so they can begin socializing?** A: What I have experience with are two cats and a dog is that they are doped up but still terrified so in my Experience its more muscular than a mental blocker so fear or terror is is still there they just can't react as fast to it .

Grazie Amazon. ### ⭐⭐⭐⭐⭐ Cautiously Optimistic *by A***R on 27 July 2022* Update: Sadly this product was only effective for a few days combined with his prescription med and then not at all, even with the max number of treats given. We ultimately had to max his dose of prescription medication and have started with a dog CBD treat. Not optimal but we are working with what we have available. I was really hopeful but hopes were dashed. I think this may work well for cats for temporary measures like a vet visit but was definitely not the answer for us. We have a 6 year old cat with significant behavioural issues. He has been under vet care for his issues for almost 4 years. We have used multiple prescription medications combined with CBD and Felaway for Friends diffusers in our upstairs and downstairs zones. These helped but definitely not a cure. Slowed his inappropriate urinating and spraying (yes he is neutered and it didn’t start until he was over 2) to sometimes once a week to once a day which was a huge improvement to what was happening at the beginning. Often times we were at a loss for what to do. We learned that the CBD cat treats we can get him to take masked with pate treat are not available with no ETA. So this brings us to trying this composure treat as an alternative. It arrived the next day as promised. He started this yesterday morning and no problem giving it to him. Boy loves them. He might be a little sad he is only getting 1 in the morning and 1 12 hours later. I really don’t know yet if it will be a long term fix BUT he was a different boy yesterday after just 1 treat. No aggression to the other 2 cats and no inappropriate urinating. He showed his affectionate side without obsession. I lowered his prescription med in half (cannot eliminate cold turkey) but hoping to be able to eliminate this med over the next few days. We will see if it works for the long term but seeing favourable results so far. Fingers crossed. ## Frequently Bought Together - VetriScience Composure, Calming Formula for Cats, 30 Bite-Sized Chews - FELIWAY® Classic Cat Calming Spray, 60ml - Comforts Cats at Home and On the Go and Helps to Calm During Travel --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/543992497-laboratories-composure-calming-formula-for-cat](https://www.desertcart.pt/products/543992497-laboratories-composure-calming-formula-for-cat) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-18*
