So i have a female 1 year old domestic cat (Lulu) and I just got a 2 month male cat. I am separating them bc i dont think theyre ready yet. I let them visit each other's rooms to sniff around, but never together. My new cat (Tito) has earmites. his ears were bleeding. We went to petco and got medication thats supposed to help. Then, i checked Lulu's ears and she has a little bit of black, no blood. I cleaned both of their ears with vinegar and water. Tito's ears are really bad though. The 2 cats never touched so I dont know how Tito gave her the ear mites. What can I do? Is a vet really necessary? Any precautions i should take? i'm so worried! Thanks
