We have just got twin silver tabby boys, George and Gilbert. We've had them a week and Gilbert has developed runny tummy and less of an appetite. I am taking them to the vets tomorrow for their first check up and vaccinations etc but wanted to know if anyone knew if this is likely to be Coccidia?? ALso, have spotted some black flecks in their fur and having put a piece onto white kitchen paper and wet it, its def flea remnants as it goes red... can i use frontline combo to treat this and the home environment or do i need a separate spray for the house? They havent been scratching or itching at all and have dark fur so didnt spot it til having had them for a week... we didnt have pets previously so think it must have come from their mum. Any tips would be greatfully received! Thank you in advance, Zoe )
