Cheristin For Cats 1 Pack, By Elanco

This product is super safe for older cats and fleas gone within 12 hours just as it says! This was the best product with no side effects for my 15yr old little lady! And affordable.

Worked so quickly! Will purchase again in the future. Worth the money!! Literally killed them within 30 min and you can see the dead fleas on their fur.

I put two tubes of this on my cat within 2 days, because I spilled the first tube onto her fur, on the back of her neck, and the first tube had no effect on stopping her scratching and red sores on her forehead. I assumed that a 2nd tube would work better, since I didn't get much of the first tube onto her skin. Big mistake! I should not have applied the 2nd tube. So applying the 2 tubes has put my cat into an altered state, where she has lost her mind temporarily. As I'm typing this my cat is running behind the computer into the cords and hiding and she has NEVER went back there before, and she won't stop crying, even though she is not vomiting and she did eat her food. She seems to be in mental shock, or in a state of trauma, and she can't stop licking herself and also whining super loud. The two tubes made her skin way more red and inflamed, although she isn't scratching herself. I think she isn't scratching because she forgot how to scratch herself, she is in a really bad confused mental shock. Physically, she seems fine, she ate her food. And has been eating, but she has been crying constantly and going into the OPPOSITE places that a cat should go. Like she climbed onto a sub-woofer and then jumped underneath my computer monitor that is sitting on my desk. Okay so what I've noticed is that cats cannot have chemicals on their skin. Anything you put on their skin can make them violently sick. I knew this from putting the brown Sulfur bath solution on her previously, which made her throw up, and was not effective. I should have known better than put 2 tubes of this product on. Please only use 1 tube, and wait 30 days (according to the instructions) before applying more. If you're having hot spots, try Chlorahexadine solution which always worked and didn't make my cat sick, but my cat HATES the smell of it and fights to get away from it. And you can also try Hypochloric Acid (Hot Spot Spray) which was effective too for small hot spots. My cat has been licking constantly and having red rashes, but I haven't been able to figure it out. My cat has red rashes above each eyebrow. My outdoor cat that interacts her has never had a single problem, and no sign of any skin issues. But my indoor/outdoor cat has a severe rash on the top of her head. The Flea medicine worked for 2 weeks, when I tried this product over 30 days ago. But it wore off quickly, within about 10 days, and then she started scratching and licking. I would avoid this product if your cat has a small hot spots. Try to confirm that your cat has fleas before using this product, because it is very potent.

Wow!! I've used so many flea products last year its ridiculous!! I came across Chetistin for cats, and it's amazing!! It didn't work in 30 minutes. However each day Max scratched less and less!! At night he would scatch and scratch no fun petting him all he would do would scratch!! Now he sleeps peacefully on my bed!! I was using advantage 2 but with that he would still scatch. It helped some but not much!! I will be ordering from now on!!! This stuff did the trick!!!

Within 12 hours I can say this flea treatment did kill adult fleas. It's easy to apply and value for the money. Definitely will buy again.
