Which kitty are you asking about? Zizu, my little rescue girl, or Bijou, my show quality Maine Coon? Zizu just topped the scales at 7.1 lbs., sooo much better than the pathetic 4.2 lbs. she weighed when I rescued her from the third-rate NJ "veterinarian" boarding her for a third-rate local rescue group back in April. Bijou usually weighs about 11.5 lbs., but with Zizu bothering her when she's trying to eat, she's lost a pound. I expect her to regain that weight when Zizu settles down a bit with maturity.
Mom had 2 cats that got along for the most part. When they had a spat, their routine was to ‘box’ each other. It looked like they were trading punches. Finally they’d break and all would be well. It really was funny to watch.
