I had two boys who are about 4 years old. Less than two weeks ago one of them passed away, from what the vet thinks was pneumonia. My other one didn't really seem to notice. I found this really strange because they were best friends. They cuddled together, played together, etc. Totally loved each other. Now we've noticed that he isn't really playing with his toys as much and he's eating twice as much. Tonight my boyfriend brought up if maybe he needs a new friend. I've read about how a new intro is pretty difficult, so I'm a little hesitant, but I really feel bad for my little guy. Suggestions...? :frown2:
