I have two indoor cats (named Darcy and Bingley) that are about 1.5 years old. This is my first time owning pets in my adult life, and I've never had an indoor pet prior to this. They are orange and white male littermates that I adopted from a local shelter. Although the kitties are lean, they are big boys, weighing in at approx 14-15 lbs.
The boys wrestle a lot and get into all sorts of shenanigans. More recently, they have started becoming very cuddly. I couldn't ask for better roommates. They are almost toilet trained - which is awesome (who likes scooping?)! Darcy will walk on a leash, but Bingley acts like he's paralyzed if I even put a harness on him. lol.
