So, here are some of my favorite stategies for coping with the heat:
Find a nice windy spot: Laying down close to the fan will make wind flow through your fur and keep you both fresh and super cute. Bonus points: humans won't be able to resist giving you a belly rub if you lay on your back and get your fur ruffled by the wind.
Save your energy: Plan your physical activity more carefully during the day. Early mornings and late evening are the best times to hunt flies, so just take it easy during the day, and find a cool spot for your afternoon nap.
Napping should become your full time job when it's hotdrink plenty of fresh water throughout the day. Next, (and I can't believe I'm going to say this...) allow your humans to help you out; let them pet you with a damp towel or wet hands. This will keep you fresh for a while, but don't show your humans you're enjoying the effects of water on your body, otherwise they might get some strange ideas. And oh, I also like to play with plastic bottle caps that float in a few centimeters of water. It's fun, and you don't even realize that you get wet while playing.
Get a good brush: Another thing your humans can help you with - it really helps to shed some extra fur! Look at how much fur I got rid of during my last session with the Furminator.
Wait... all that fur was on me?!?
Aaah, getting some real wind in my fur during a cloudy day
I hope you find some of these tips useful; and please let me know if I'm missing anything important in the comments! Now, if you'll excuse me, I've got a nice, cool spot waiting for me underneath the fan...
