Adorable picture. Yes,there sure is size difference and if I can ever get a picture of both of my girls together it would look something like your Steve and Gigi. Pearl is 9lbs and Ziggy is (or at least was on Sun. June 13th) a whopping 15.9lbs. She's now on a much needed diet and my vet wants her to lose at least 2 lbs. Storm is my largest cat in length and is about 14.1lbs and Sky also weighed 13.5lbs as of June 13th so I have to watch his weight too.

For the past 2 years, I've been taking my 3 long haired cats to the groomers for annual lion cuts. This really helps them stay much cooler in the summer and I don't have A/C either. I already made an appointmet for Sat. July 3rd so hopefully everything will go well. Maybe you could try a lion cut out on Steve. It takes about 5-6 months for their fur to grow back completely which works out great because this is when it starts getting much cooler again.
