So ... we spend a lot on heat and AC because the wife is insistent, so our house is a fairly constant temperature, more or less. I recall our indoor/outdoor shedding more in the heat of true summer, and seem to vaguely recall our past indoor only kitties shedding more in summer as well. Its only March 22nd now, and our 7 month old medium-hair kitten (our first non-shorthair) is shedding A TON in the last week or two! Its crazy! How does her body know what the temperature is outside? Its the same temperature inside (more or less)! Its not even been above 70 outside, just a few days in the 60s.
