Flea prevention for cats when you travel often

If you're travelling frequently and need flea prevention that can look after itself while you're away, that's a really sensible thing to plan ahead for. Before I get to a recommendation, one important safety note: cat flea treatment has a critical difference from dogs — permethrin and certain other insecticides that are safe for dogs are toxic to cats and can be fatal, so it's essential to use a product labelled specifically for cats. Now, a couple of quick questions: how old and how heavy is your cat, is this about preventing fleas or dealing with an active infestation, and have you treated your home recently?

That's really helpful. A 4kg adult Tonkinese on pure prevention, with gaps of up to a month between someone being around — that changes the recommendation quite a bit. Monthly spot-ons are fine when you're home to apply them, but if your friend isn't comfortable doing it or if the timing drifts, you lose coverage. What I'd want to know: is the friend who checks in able and willing to apply a spot-on treatment if needed, or would you prefer something you apply yourself before you leave each time?

Perfect — that makes the decision clear. I'd recommend Bravecto Spot-On for Cats. It's a single spot-on treatment that provides 12 weeks of flea protection, so if you apply it before you leave, your Tonkinese is covered for the whole trip and well beyond. It's a prescription product in the UK, meaning you'll need to get it from a vet or an online vet pharmacy, but that's straightforward and actually a good reason to register with an online vet service if you travel a lot. It contains fluralaner, which is safe and well-tolerated in cats, and at 4kg your cat falls comfortably within the standard dosing range. Apply it to the back of the neck as you would any spot-on, and you're done for three months. For a cat that's indoors most of the time and not mixing with other animals, one treatment before each trip will likely give you complete peace of mind.

Garden access does raise flea exposure slightly compared to a fully indoor cat, but Bravecto's 12-week duration is designed precisely to cover that kind of normal outdoor contact. Fleas she picks up in a garden are very unlikely to establish an infestation when she's on a continuous prevention product — they're killed before they can lay eggs. Where you'd want to revisit things is if she were regularly mixing with stray cats or other animals, but a small private garden is low risk. Stick to the 12-week schedule, and you should be well covered.

You're all set. Your vet will confirm the dose for her weight — at 4kg she's well within the standard range — and many will issue a repeat prescription so you can order it through an online pharmacy between trips, which is handy when you're busy. Enjoy your travels.
