Can cat owners really do without those supplements? Your cat is taking more supplements at a young age than my grandmother does. Now let me ask you: do you even know how these supplements are made? Are you aware which ones are effective and which ones are not? Some supplements indeed benefit cats when administered, yet there are others which, when overconsumed, can truly do more harm than good. Today, this article will explain when your cat should receive these supplements and when you should definitely avoid them.

Pet-Specific Vitamin Tablets — Unnecessary to Buy
“You create a need for your customers, and only then will they purchase your product.”
“During the processing of cat food, vitamin B is lost, so you must supplement it; otherwise, a long-term diet of cat food may lead to vitamin B deficiency in cats.”
It is true that vitamin B can be lost, but does it just vanish? Have you ever seen a number of cats on a long-term cat food diet develop vitamin B deficiency? Unless the cat food itself is nutritionally inadequate and of poor quality, even if your cat is truly deficient in vitamin B, a vitamin tablet from a pharmacy costing just a few dimes will suffice—you don’t need to buy a so-called“pet-specific”version.
Calcium Supplements — Don’t Overdo It, or You Risk Causing Harm
Whether it’s liquid calcium, solid calcium, or calcium tablets, cats should not be given extra calcium without reason, especially kittens! It is true that kittens have higher calcium requirements; however, the calcium content in cat food is usually sufficient and does not need additional supplementation. You must understand the concept of the calcium-phosphorus ratio; calcium and phosphorus must be considered together and should not be supplemented in isolation.

Cat food manufacturers have already optimized the calcium-phosphorus ratio for you; supplementing extra calcium can upset that balance and lead to developmental imbalances in your cat. Moreover, excess calcium that a cat cannot absorb will deposit in the body, causing significant harm.
So does supplementing calcium simply amount to an unnecessary expense? Not exactly! If your veterinarian clearly advises that your cat needs additional calcium, then supplementing is perfectly fine.

Trace Element Tablets — Pica Does Not Equal a Trace Element Deficiency
Does your cat nibble on plastic bags? Lick the walls? Is your first reaction to buy trace element tablets? Many people, upon noticing such behavior in their cats, immediately search online for a solution, only to find that“trace element tablets”are touted as a universal answer.
In reality, nine out of ten cats display such behavior simply because they are a bit bored—not due to a lack of trace elements. Up to now, I’ve been asked this question by at least seventy or eighty people, yet only one or two have seen any benefit from trace element tablets.
If your cat exhibits pica, you can try giving it some trace element tablets to see if there’s any improvement; if it works, use them, and if not, then drop it—don’t place blind faith in them.
Fur Growth Powder and Cheek-Enhancing Powder — Don’t Get Ripped Off
These two products still exist on the market, entirely propped up by inexperienced, novice owners. A cat’s propensity for“fur explosion”or“cheek enhancement”is purely determined by breed and genetics.
Especially with fur explosion, it is entirely genetically determined—no powder can change that. As for cheek-enhancing powder, if it truly could supplement male hormones, then there might be an effect. But the reality is that the products available on the market simply do not contain such components, so stop wasting your money.

Fish Oil — A Good Product, but Don’t Overdo It
Fish oil is indeed beneficial—it supports cardiovascular and brain health and helps cleanse blood lipids, provided the concentration is high enough and it is not given in excess. Most of the cheap“fish oils”on the market are blended with other oils and lack substantial nutritional value.
How to Choose the Right Fish Oil?
| Key Factor | Explanation |
|---|---|
| Fish Oil Concentration | Pay attention to the Omega-3 concentration; if it’s too low, it’s ineffective. |
| Ingredient Safety | Avoid fish oil of unknown origin or those that are excessively cheap. |
In addition, many novice cat owners, upon noticing poor fur quality in a two- or three-month-old kitten, immediately think of giving fish oil. But can such a young cat really digest it? Won’t it cause diarrhea? When cats run, jump, or even pass gas, wouldn’t the oil just spill out? This is truly no laughing matter.
Don’t Overcomplicate Cat Care—Save Money and Keep It Simple
There is a saying that, though its words may be rough, its meaning is true: After new cat owners bring their cat home, once you’ve purchased cat food, a litter box, and litter, everything else is really optional. Stop fussing over unnecessary extras; all that extra effort will only leave you exhausted and still unable to properly care for your cat.
