Oh Kallie, pretty calico girl, calicos are my absolute favorite! I'm so sorry that this has happened to you. As there, it's warming up here but I still keep my space heater on low for my 19 year old Pigeon because she likes to stretch out in front of it. We do what we can to keep our senior kitties as comfortable as possible. I have experience w/deaf cats (and my Coco just lost his hearing; we're hoping it's temporary) but never deaf and blind cats, so I don't have any advice for you other than to continue making Kallie feel as secure as possible. Possibly your vet can help you out w/advice. My prayers are going up for sweet Kallie and you.
