Dexter, like all of my cats are strictly indoors. We have a specially fenced back yard with a cat-topper for them to get some exercise in our tiny back yard on warm days .... so , no ... his ear didn't get frozen. hehehe

Dexter had a hematoma on his ear and had to have surgery to drain it. A hematoma is when a blood vessel bursts internally (from scratching or trauma) and if it ruptures, his whole ear would have crinkled and died. You've probably seen pictures of cats with crinkled ears before!?

Thankfully, we got Dexter to surgery right away and were able to save his ear ... he just has a little extra purrsonality in that ear now!
