They said they separated the new ones from the ones that have mites, should I still be worried ?
I do have two rats already, I quarantined the new one upstairs behind a sealed door and a bathroom door so its pretty far away. But the girl at the pet store said they didn't have mites and that they saw a cluster of them on the infected rats so that's how they knew. Idk why they would lie about that . unless they aren't mites but something else.If the store has mites, most likely all of the rats have mites. If you don't have any rats or mice at home yet, you can buy the rat or rats you like and treat them with revolution, if you already have rodents at home, you will be bringing mites into your house and will need to do a very strict quarantine or and most likely have to treat everyone.
Also wash your hands and change your clothes after handling any pet shop rats, you can carry the mites home on your person.
