Is Hartz hairball shampoo for cats dangerous?

I have seen posts all over the internet about the Hartz flea and tick stuff being really dangerous for pets. I will never use anything off the counters for fleas or ticks on my pets, only the stuff I get from the vet. However, I haven’t seen anything about the Hartz shampoo for hairball control for cats. Is it dangerous? Has anyone had an experience with this? Please answer, I am worried because I didn’t really know about how dangerous Hartz can be until after I gave my cat a bath.

  1. If it has “Hartz” on the label, it’s dangerous. That product specifically might not be dangerous, but giving money to Hartz is a bad move.

  2. What’s in the shampoo?
    If it contains essential oils such as tea tree, it’s toxic for cats. D-limonene is also toxic & is present if citrus is mentioned. Does it contain any harsh ingredients? Check the EWG website for a rundown on ingredient safety.

    How does it control hairballs? Any cat safe shampoo will help loosen dead fur. Does the Hartz product contain some type of follicle damaging chemical to release fur from skin?

    If ingredients aren’t listed, don’t use it. If you call for ingredients & all they give you is an MSDS list that just says types of chemicals (such as coconut based surfactant) without naming the specific chemical, don’t use it.

    1. This hairball control killed my beloved cat last night and I’ve been doing research ever since. You are right to say stay away from all hartz products! We are devastated!!

      1. It killed my cat too. I was so sad and didn’t even think about it being the shampoo until a vet tech I was talking to said that some shampoos could be dangerous. I googled and found this website.

  3. We had started an in home pet grooming business. About 3 months in we got a request from one of the owners to use a hairball treatment on their cat. We had never done this and thought that it was a good idea to just use on all of the cats we were grooming that particular day. We had 12 cats that day and we treated reach one with hartz hairball shampoo. The way our business worked is the owners would drop off their pet before work and then come pick them up when they got off. We started washing the cats right at 9am like we normally would. We finished washing and grooming all 12 cats by 1:45ish. We started noticing that some of the earlier cats that we washed were acting kind of lethargic around that same time. It was nothing new since cats put up a physical and mental fight when grooming them. However by 2:30pm we noticed that 2 of the cats were not breathing. We tried everything that could come to mind to get them breathing again but nothing worked. One by one 11 out of the 12 cats that we had in our care, died. It was probably the worst day off our lives. We lost everything over the next few months. I’m never ever touch another cat for the rest of my life.

  4. My kitten is acting lethargic. Thought maybe worms… but after deworming started thinking something else might me happening. Looked up shampoo and sure enough. This is bullshit that they would be selling a product for cats that can kill them! Pissed!!!
