This is a specific conversation about Flea treatment for cats — safe and effective options — ask about yours and get one honest answer for your exact situation.

Before anything else, one safety point that's critical with cats: permethrin and several other insecticides that are perfectly safe for dogs are toxic to cats — sometimes fatally so. Always check a product is specifically licensed for cats before using it. Now, fleas and overgrooming are a rough combination — the irritation from bites can spiral compulsive licking into something much harder to manage. To point you toward the right treatment, can you tell me how old and how heavy your cat is, whether this is an active infestation or you're trying to prevent one, and have you treated your home environment yet?
She's a 5-year-old Egyptian Mau, about 4.5kg. It's definitely an active infestation — I can see the fleas. She already had a history of overgrooming but it's got much worse since the fleas appeared. I haven't treated the home yet, I only just realised what was going on.

That makes a lot of sense — flea allergy dermatitis is one of the most common triggers for overgrooming to escalate, and Egyptian Maus can be quite sensitive cats temperamentally too, which doesn't help. A couple of quick questions: has she been on any flea treatment recently, and is she currently on any medication — particularly anything for anxiety or the overgrooming itself, like gabapentin or a tricyclic?
No flea treatment recently, that's partly how this happened. She's not on any medication at the moment, though her vet has mentioned considering something for the overgrooming before. Nothing prescribed yet.

Good to know — no interactions to worry about then. For a cat in her situation, I'd recommend Bravecto Spot-On for Cats (250mg for cats 2.8–6.25kg). It's a single spot-on that kills fleas within 12 hours and stays effective for 12 weeks, which is a real advantage here. With overgrooming, you want to break the itch-lick-itch cycle as quickly and completely as possible, and the fast kill speed and long duration mean she's not getting repeated bites keeping that cycle going. It's also a fluralaner-based product, which is well-tolerated in cats and has no known issues with anxious or compulsive-behaviour cats. Apply it to the back of the neck so she can't lick it — that matters even more given her tendency to overgroom.
That sounds good. What about treating the house — do I need to do that at the same time?
inparticular.ai
Yes, and it's genuinely important — around 95% of a flea infestation lives off the cat in soft furnishings, carpets and bedding, not on her. If you only treat her, you'll keep getting reinfestation. Use a household flea spray that contains an IGR (insect growth regulator) — Indorex Defence Household Flea Spray is the most reliable option widely available in the UK. Spray all soft surfaces, vacuum first to activate dormant pupae, and wash her bedding at 60°C. One thorough treatment alongside starting Bravecto should break the cycle. Once the flea irritation is gone, it's worth revisiting the overgrooming with her vet — some cats do need additional support if the behaviour has become ingrained even after the trigger is removed.
Really helpful, thank you. I'll get both sorted today.

Good plan. Apply the Bravecto today, do the house spray the same day if you can, and keep her out of treated rooms for about an hour while surfaces dry. You should see a significant reduction in her scratching and licking within a day or two as the fleas are eliminated. If the overgrooming doesn't settle down within a couple of weeks once the fleas are gone, that's a good prompt to go back to her vet — it's easier to assess what's behavioural versus flea-driven once the physical trigger is fully removed.
