Wanted to confirm something - even in cycles where the first test is at +6 or so, he gets food before, right? That is, between PS and +5/+6?
Found this on Tanya's website (www.felinecrf.org) when I was reading about Hypertension in cats:
"Red and/or Hot Ears
A number of people have reported this symptom over the years. In all cases, the cat has turned out to have hypertension, often with a systolic reading over 200 mm Hg. Alternatively, red ears are sometimes seen in cats with food allergies."
Hi Kim, my first thought about Gus’s ears was a poultry allergy. Maybe you could poach up some bland minced pork for him to eat for a few days to see how he reacts? Pork is one of the most hypoallergenic meats out there because it’s not a very common ingredient in manufactured cat foods so they don’t develop allergies to it. Instead of the canned HC you’ve been feeding, you can mix honey or Karo with LC. This is what a lot of caregivers do when their cats have allergies to ingredients in high carb food.
