Am brand new! Have 5 girls, all fixed and are indoor outdoor cats way out in desert in Texas, no roads or cars. I have one black girl who is doing the weird low held ear thing! Looks clean, no mites, healthy cat! Me too I am stumped?
Glad that you've joined us. Do check out the site as it has lots of good reads and informative threads.
When you said your kitty weird low ear held thing, does she scratch it or is she holding her head down? You have a photo? Maybe a photo would help and some others with better experiences with cats might be able to tell what's wrong. If it's not bothering her, just leave it for the moment and if you are concern that it's a medical issue, have a vet take a look at lt.
