I wish I'd known about this stuff a year ago when Patches first came home with Sue.

Given that they've been at it for a year, do you think that it would still be worth trying at this point?

The issues between Patches and Stella seem to be about food (Patches weighs 15 pounds and would like to bulk up to 20, she seems to feel that all of the food should be hers), territory (they each have their own areas that the other doesn't venture into any more), and attention from humans (fights often start when one of the two is sitting on Sue's lap.)
