Best Cat Calming Treats Buying Guide & FAQ

Things to Look for in Cat Calming Treats

As cat calming treats feature a different ingredient list in comparison to ordinary cat kibble, even seasoned cat owners don’t know where to start when scrutinizing the label for signs that the cat calming treats they’ve set their eyes on is of high caliber. Detailed below, we’ve formulated two questions to ask yourself when in this very situation.

What are the active ingredients included in your prospective cat calming treats?: For cats in particular, the best active ingredients that set cat calming products apart from the rest are described below.

L-Tryptophan: This amino acid naturally occurs in many proteins. Its greatest benefit for cats is its role in creating neurotransmitter serotonin. Although buyers may be perplexed when D-Tryptophan appears on the label, the only real difference between both forms of this amino acid is the orientation of the molecule. Put simply, the D at the front of D-Tryptophan is derived from the Greek prefix dextro, meaning “right”. Surprisingly enough, the L at the beginning of L-Tryptophan doesn’t actually mean “left” – it’s similarly derived from the Greek prefix “levo” which, of course, means left. Anyway, both forms of the essential amino acid are fantastic for cats, and even create vitamin B6, which is essential for energy metabolism.

L-Theanine: This fantastic amino acid has a fast calming effect on cat. Thankfully, all chewable tablets containing this amino acid have presented themselves as a palatable option for cats who need it.

How often can you feed these cat calming treats to your stressed out kitty?: For cats who spend their entire day impacted by anxiety, only feeding cat calming treats to them at night won’t be enough to calm them down. Accordingly, it’s essential to check the frequency to which these tablets can be administered to your cat.

Benefits of Using Calming Treats for Cats

They have been scientifically proven to calm down kitties: Cat calming treats aren’t another one of those marketing products that were advertized so hard buyers started to believe that they worked. These products actually work for when your cat finds themselves in a stressful situation or suffers from chronic anxiety. The overwhelming amount of evidence speaks for itself. One prominent 2018 study published by the Irish Veterinary Journal found that administrating amino acid L-Theanine to thirty-three stressed out cats for a month dramatically improved undesirable manifestations of stress in cats, of which shaking, inappropriate elimination, and overall mood were among them.

Treats can be used as a positive reinforcement technique: All cats – stressed-out or not – love when their owner gives them human attention, despite what most people think! Giving them treats won’t only help them combat stressful situations, you’ll simultaneously be able to demonstrate to your feline that you care.

Best Cat Calming Treats FAQ:

Q: How can I tell if my cat is stressed out?

A: We’ve highlighted a number of symptoms of anxiety below, as well as including other possible causes for these symptoms to have arisen. Our intention isn’t to suggest that the diagnosis of your cat may be incorrect; we simply don’t want you to jump to conclusions when there may be other reasons why your cat isn’t themselves.

  • Physically shaking: If your cat physically shakes at times, this does indeed points towards the fact they’re stressed out. This is one of the easiest anxiety signs to spot.
  • Sores and lesions on their skin: Although a reaction to medication and poor grooming may also cause sores and lesions to form, anxiety is another common explanation.
  • Failure to produce solid stools: If a cat isn’t mentally or physically healthy, their poop should be one of the first indicators that something isn’t quite right. Other reasons for loose stools can be a change to a cat’s diet, or even Inflammatory Bowel Disease.
  • Not using their litter box: If your cat’s failure to use their litter box is the only symptom, remember that cats are clean animals and hate to be amongst mess – even if that mess is their own!

If your cat is displaying the vast majority of these symptoms, chances are they’re stressed out. However, due to the plethora of illnesses these symptoms are associated with, we recommend taking your cat to their veterinarian for a proper diagnosis. Not only will you stop worrying over an incorrect diagnosis, your vet will be able to rule out any underlying issues that may be provoking anxiety in your pet.

Q: How can I calm my cat down at night?

A: In no way should you punish your cat for being anxious. This certainly won’t help them and, most likely, will exasperate their anxiety. Therefore, throughout every stage of the process, be kind and treat your kitty with the utmost kindness.

Create a cozy spot for your stressed-out kitty to relax in: As many breeds of cat are tree-dwellers, being elevated at night may help them relax. To this end, buying your feline a cat tree or elevated bed may make them feel more in control. Your cat’s brand-new elevated bed should be tucked away someplace in your home that doesn’t see much footfall.

Streamline the positioning of your cat’s essentials: If your anxious cat’s litter tray is all the way down in the basement and their cat food in the kitchen, the thought of making their way to each corner of the house is enough trigger chronic stress. Although placing a litter tray in your bedroom is a horrifying thought, it’s a small sacrifice to ensure your cat becomes less anxious and sleeps through the night.

Calming essential oils induce sweet dreams: If your anxious cat struggles to calm down at night, there are natural cat calming products out there to help them, such as calming essential oils. Honeysuckle and lavender oil in particular has been renowned for making stressful situations a little less nerve-racking. In fact, vets even state that when they’re dealing with an aggressive cat in the examination room, they often put a few drops of lavender oil on a paper towel to calm the cat down.

Give your cat calming products: We wish to finish off our buying guide by reiterating the power of the cat calming products displayed in our product selection. Just one chew a night will allow your beloved feline to relax and transform back into the cat you know and love.
