Pet's info: Cat | Mixed Breed | Male | unneutered | 6 years and 3 months old

Hi,I have to put Bravecto on my cat after a week but I need advice for the dose because his weight vary a lot,he's very tall and very long with big muscles and bones and his weight is around 7 kg,with winter coat up to 8-9 kg and in the summer around 5 and 1/2-6,but this summer he's very thin only 4 kg,if I put the dosage which is from 2 to 6 kg is that will be enough to the middle of November when he might be more than 6 kg? And is it normal because he's active that he lost half of his weight?

2-6 Kg is the amount he needs, if you use the dosage above this one you are risking toxicity. it is not normal at all to lose more than half of his weight, i would say it is very likely that he is suffering from a disease in the background that is causing this, i strongly recommend taking him to the vet ASAP in order to get it checked.
