My cat has fleas and irritated skin. How can I relieve the itching?

Updated On September 23rd, 2025

Pet's info: Cat | Persian | Female | 1.025 lbs

Hello, ma cat has fleas. I have tried literally everything. I have used up 3 big bottles of Frontline spray on him but I can’t get rid of it. He developed allergic reaction to fleas lately. He keeps scratching his back all the time. Skin looks irritated. So my question is, can i use Fenistil gel( dimethindene maleate) to help him relieve the discomfort and itchiness? Before his skin gets healed and i can try again anti flea medicine. P.S i know it’s not something else, we’ve been to vets before

I am afraid, Fenistil will not help. The only thing that will help is to get rid of fleas in your house and make sure your cat does not get bitten any more. Here is how to get rid of fleas once and for all: Unfortunately fleas only hop on the body of your pet when they want to feed, then they hop off again and stay in your pet's environment. So you need to treat all pets in the household as well as the environment (which contains the fleas, their eggs and larvae). Flea treatment:  1) Get some flea medication such as a Flea spray or a spot on from a pet shop or your veterinarian and apply monthly 2) get flea powder, put some in your vacuum cleaner bag and vacuum your house and furniture and also non-carpeted areas frequently to remove flea larvae and eggs which live off house dust., Dispose of the bag in the trash outside. Hot-wash all the pet's bedding, If you do this diligently for a few months you will get rid of the fleas. Flea products: Spot-ons and/or chews Advantage, Advantage Multi Bravecto spot on (ticks as well) - for cats, Simparica, Nexgard Revolution Tablets: comfortis (will only kill fleas once) Collar: Seresto (ticks as well) House spray: Indorex
