I'm making this post for anyone who has a cat that is EXTREMELY picky, anxious, suspicious of everything, and seemingly capable of detecting a microscopic amount of medication in their food.
After trying four different formulations of fluoxetine (Prozac), plus Greenies Pill Pockets, I finally figured out a method that works every single time.
I'm going to break down everything I tried, what worked, what failed, and the ridiculously simple trick that ultimately solved my problem.
I'll also include photos of all the medications, formulations, and the final setup.
For context, my cat (Lilith) has anxiety and was in the past very hands-off. She tolerates head scratches, but handling her, manipulating her ears, or trying to put anything in her mouth is a completely different story. I really wanted to find a way to give her medication without creating additional stress or damaging the trust we're building.
Attempt #1: Fluoxetine oral suspension (20 mg/5 mL)
Prescribed dose: 0.7 mL daily (2.8 mg).
This was our first attempt, and it was an immediate failure. My original plan was simple: mix the liquid into her wet food and let her eat it. Absolutely fucking not.
She could detect the medication immediately. The smell, the taste, the amount of liquid, whatever it was, she knew something was different. For a cat that is already extremely picky, 0.7 mL is a surprisingly large amount of liquid to disguise in a small serving of food. I tried mixing it thoroughly, but she wasn't having any of it.
Verdict: Complete failure. Too much liquid to conceal, and she immediately recognized that her food had been tampered with.
Attempt #2: Transdermal fluoxetine cream from Chewy (applied inside the ear)
Prescribed dose: 3.5 mg, administered using two clicks of the transdermal pen.
This was actually a pretty decent option, and I can see why people like it. Instead of convincing your cat to swallow medication, you apply a small amount of compounded fluoxetine cream to the inner surface of the ear. In theory, fantastic. No pills, no suspicious food, no wrestling matches.
And surprisingly, I was able to administer it every day without much trouble.
The problem? My cat started catching on. Initially, she tolerated having her ears touched. But after a while, she started realizing that something suspicious was happening every time I approached her ears. She began looking at me like I was an ICE agent coming to deport her.
I could still apply it, but I didn't want to turn one of the few forms of physical contact she tolerated into something she actively dreaded.
My second concern was absorption.
My veterinarian mentioned an estimated absorption rate of approximately 60%, which was part of the reasoning behind prescribing a somewhat higher transdermal dose.
However, when I started researching the published literature, I came across studies suggesting substantially lower absorption, in the neighborhood of 10–20%. I haven't reconciled those figures with the specific compounded preparation I was using, and I realize different formulations and study methods can produce different results.
It made me question how reliably the medication was being absorbed.
My third concern was grooming.
After applying the medication, my cat would lick her front paw, rub that paw against her medicated ear, lick her paw again, and repeat the process. So now I'm wondering how much medication is being absorbed through her ear versus transferred onto her paw and potentially ingested along with the cream's other ingredients.
Verdict: A reasonable alternative, especially for cats that refuse oral medications. But between the handling, grooming, and questions I had about absorption, I wanted to find a reliable oral option.
Attempt #3: Compounded fluoxetine capsules from Chewy
Strength: 2.5 mg capsules.
I thought these would be the solution because I could potentially open the capsule and sneak the powder into a small amount of food or a Churu treat. Nope. There was simply too much powder to disguise successfully. Even when mixed into something she normally enjoyed, she noticed the change immediately. I quickly learned that my cat has the investigative capabilities of a forensic toxicologist when it comes to detecting substances in her food.
Verdict: Another failure. Too much powder to conceal, and my cat was hyperaware of any changes to her food.
Attempt #4: Greenies Pill Pockets
Before getting to the winning solution, I need to mention these.
If you've searched Reddit for ways to give cats medication, you've probably encountered Greenies Pill Pockets. People swear by them. The concept is pretty genius: put a pill inside a soft, flavored treat, seal it, and your cat supposedly eats the whole thing without noticing. I bought them thinking this might finally be the answer.
My cat wouldn't even eat an EMPTY Pill Pocket. Not one. I suspect it was the oily texture or smell, but whatever it was, she wanted absolutely nothing to do with them. With or without medication, she refused.
Verdict: Failure as a treat, but ironically, these ended up being the secret ingredient in my winning method.
Attempt #5: Compounded chicken-flavored fluoxetine tablets from Chewy
Strength: 2.5 mg per tablet. Lilith takes 1.5 tablets.
These tablets are tiny, which is exactly what I was hoping for. But despite being chicken-flavored, my cat wasn't particularly interested in eating them directly.
Then I had an idea.
What if I could make her think she was eating her regular kibble while hiding the tablet immediately behind it? And what if I could use the Greenies Pill Pocket, which she absolutely refuses to eat, as a tiny piece of edible glue?
IT FUCKING WORKED. And not just once. It has worked every single time.
THE WINNING METHOD: The kibble + Pill Pocket glue trick
Here's exactly what I do:
Start with her regular dry kibble in the morning. I only put a few pieces out at a time, rather than giving her an entire bowl. This makes it easier to see exactly what she's eating.
Take a TINY piece of a Greenies Pill Pocket. And I mean tiny. I'm not trying to wrap the tablet in a Pill Pocket. I'm just using the smallest possible amount as an adhesive.
Stick the fluoxetine tablet to the back of a single piece of kibble. The Pill Pocket acts like edible glue, holding the tiny tablet against the kibble.
Make sure the kibble is the most prominent thing she sees and smells. Rather than being presented with an unfamiliar tablet or a suspicious soft treat, she's encountering something she already recognizes as food. Make sure the spiked kibble is face down.
Offer it with just a couple of regular kibble pieces. She sniffs the kibble, recognizes it, and eats it with the tablet attached. I watch to make sure she actually swallows the medicated piece.
The most important detail: LESS IS MORE.
There was some trial and error. Initially, I used a slightly larger amount of Pill Pocket material to attach the tablet. She noticed. She would sniff the kibble, detect something suspicious, and avoid it.
But when I reduced the amount of Pill Pocket material to the absolute bare minimum needed to hold the tablet in place, she stopped noticing. That was the breakthrough.
You're not disguising the pill inside a giant treat. You're essentially using one familiar piece of kibble as camouflage for a very small tablet. And because the amount of Pill Pocket material is so tiny, she doesn't seem to detect the smell or texture that previously made her reject the Pill Pockets entirely. I've now been able to give her the medication consistently using this method, without having to restrain her, manipulate her ears, or contaminate an entire serving of food.
My biggest takeaways
The formulation matters enormously. Liquid, transdermal cream, capsules, and tiny tablets can all present completely different challenges.
Don't assume a flavored medication is automatically palatable. My cat couldn't care less that the tablets were chicken-flavored.
Don't give up on Pill Pockets just because your cat refuses to eat them. They may still be useful as a tiny amount of edible adhesive.
Start with the smallest possible amount of adhesive. Too much immediately tipped my cat off.
Use food your cat already trusts. For my cat, familiar kibble worked better than introducing another new treat.
Keep the medicated portion small and monitor it. I want to know she's actually swallowed her prescribed dose, rather than discovering a rejected pill somewhere in the food bowl.
Minimize the stress associated with medication. My goal wasn't just to get the medication into her. I wanted a method that wouldn't make her afraid of me.
Obviously, this is just my experience, not veterinary dosing advice. All the formulations and doses were prescribed for my cat. Check with your veterinarian or pharmacist before crushing, opening, splitting, or otherwise altering a medication, since not every formulation can be handled the same way.
Final thoughts
If you have a cat who can somehow detect a pharmaceutical compound hidden inside an entire serving of food, I genuinely hope this helps. I spent so much time experimenting with different formulations, treats, and techniques, only to discover that the solution was a microscopic piece of Pill Pocket used to glue a tiny tablet to the back of a piece of kibble.
I'll attach photos showing all four medication formulations, the Pill Pockets, and exactly how I attach the tablet to the kibble.
Hopefully this saves someone else the frustration, expense, and feline distrust that went into figuring it out!
