Why trust this review
I am a DVM and a board-certified veterinary nutritionist, which means I spend my working life reading pet food labels the way an accountant reads tax code. I have formulated therapeutic diets, counseled owners through feline kidney disease and obesity, and watched too many well-meaning treats quietly push a cat into a weight problem. So when I evaluate a product like Hartz Delectables Lickable Wet Cat Treats, I am asking two questions at once: do cats actually love it, and does it earn a place in a responsible feeding plan.
I bought these tubes at retail with my own money. No part of this review was provided or influenced by Hartz. If you buy through my link I may earn a small commission, but that does not change what I tell you about the calories or the ingredient deck.
How I tested Hartz Delectables Lickable Wet Cat Treats
I tested the tuna and chicken lickable varieties over four months on three cats with deliberately different profiles. The first was a healthy 4-year-old domestic shorthair, food-motivated and easy to please. The second was an 11-year-old spayed female with early-stage kidney changes and a famously picky appetite. The third was a slightly overweight 6-year-old who needed strict calorie accounting.
I offered the puree three ways: directly from the tube, smeared on a lick mat, and as a wrapper for a placebo pill to test the medication-hiding use case. I tracked acceptance, stool quality, and whether the treats nudged any cat away from balanced meals. I also weighed the overweight cat weekly to confirm the treats were not derailing her diet.
Who should buy, who should skip
Buy these if you have a cat who under-drinks, a senior who has gone lukewarm on food, or a pet who fights medication. The format is a genuinely useful tool, and the price per tube is friendly.
Skip these, or at least restrict them sharply, if your cat is overweight and lacks discipline at the bowl, or if your cat has been prescribed a therapeutic diet for kidney or urinary disease. In those cases I would route you to a single-ingredient lickable or a vet-recommended option, because the added flavoring and sodium here are not what I want layered on top of a medical diet.
Palatability: the strongest reason to buy
This is where the product earns its rating. All three of my test cats came running for the tube within a week, and the picky 11-year-old, who routinely snubs premium canned food, licked her tube clean every single time. For a cat with a declining appetite, that reliability is clinically valuable. I have far more tools to work with when a senior will eat something enthusiastically.
The puree texture is smooth and pourable, which makes it ideal for lick mats and slow enrichment feeding. Acceptance was effectively 100 percent across my small sample, and that is not something I say often.
Ingredient quality: good enough for a treat, not for a meal
Here is where my nutritionist hat tightens. These tubes lead with a named protein, tuna or chicken depending on variety, which is what I want to see. But the deck also includes thickeners and added flavor, and the product carries a treat designation rather than an AAFCO complete and balanced statement. That distinction matters. A treat-labeled product is not formulated to meet a cat’s full vitamin, mineral, and amino acid needs, so it cannot stand in for a meal.
In practice this is fine, because that is exactly how a treat should be used. My objection is only to owners who let lickable tubes creep toward replacing real food. They are a topping and a tool, not a diet. For guidance on balanced feeding, the AVMA pet owner resources and ASPCA nutrition pages are reasonable starting points before you talk to your own vet.
Hydration and medication value: an underrated upside
At roughly 88 to 91 percent moisture, each tube delivers a small but real amount of free water. For cats with early kidney changes, like my senior tester, every bit of incidental hydration helps, and a treat she actively wants is more reliable than a water fountain she ignores. I would never call this a treatment, but it is a sensible supporting habit.
The medication test went well too. The puree fully concealed a placebo pill, and the cat licked it down without noticing. Just confirm with your veterinarian that the specific drug can be given with food, because a handful of medications must be dosed on an empty stomach.
Measurements that matter
The number I care most about is calories. Each tube runs roughly 10 to 12 kcal. For an average 10-pound indoor cat eating about 200 calories a day, the 10 percent treat ceiling lands near 20 calories, which means one to two tubes is the responsible daily maximum. That is easy math, and the single-serve format makes portioning honest, but the catch is behavioral. Every cat I tested begged for more, and an undisciplined owner could easily double the dose.
Stool quality stayed normal across all three cats, with no loose stools or vomiting over four months. My overweight tester held her weight steady because I counted the tubes into her daily total rather than treating them as free. That is the whole game with any treat: it only stays harmless if you account for it.
Compared to the churu-style category leader, these are slightly less refined on the ingredient deck and a little cheaper. If budget is tight and your cat is healthy, that trade is reasonable. If your cat has a medical diet, I would spend more for a cleaner option.
How this product has changed
Lickable puree treats as a category have matured fast. A few years ago the segment was dominated by one or two premium imports, and Hartz Delectables Lickable Treats represent the format reaching a mainstream, lower-cost price point. The current tubes I tested are consistent in texture and palatability, and I saw no quality drift across the batches I purchased over four months. I will update this review if Hartz changes the formula, adjusts the calorie content, or if any recall or safety advisory is issued. As of this writing I am comfortable recommending them in moderation as a treat, a hydration helper, and a medication vehicle, with the firm caveat that they are never a substitute for a balanced meal.
