My late boy Terry was the same color as yours. Johnny only tried to chase him and his brother once, when they were playing. NO CAT, I yelled, he stopped. Terry was never the bravest of the bunch, he was more likely to hide than swat, but the others showed Johnny that cats are ouchy and to be avoided. I agree with the others, slow intros and muzzles to start.
All bets are off with outdoor cats, he thinks our local strays/ferals are super interesting, regardless of the color. Squirrels are boring, but possums and raccoons are worth a look.
