A small rodent showing signs of parasites is often noticed later than a dog or cat would be, simply because there's less coat to check and less handling day to day. By the time scratching or fur loss is obvious, an infestation is usually already established.

Petsolve's Anti-Parasite Small Rodent spot-on is labelled for use against ear mites, fur mites, mange mites, lice and worms in hamsters, gerbils, mice and rats weighing over 50g. It's supplied as a 10ml bottle containing 100 drops, applied by parting the fur and placing it on the back of the neck, between the shoulder blades. Petsolve's own dosage guidance is one drop per 50g of bodyweight, once a week, for three weeks.

Before you use it. This is for animals over 50g specifically, and Petsolve's own dosing scales with weight - if you're unsure of your animal's exact weight or whether it's suitable for a very young or underweight animal, weigh it first or check with a vet before applying.

Who it's for: owners of hamsters, gerbils, mice or rats over 50g dealing with a suspected or confirmed parasite problem, following the manufacturer's weekly weight-based schedule.
