Actually, Ram has a good point. Getting a new pet will help fill that empty space. I know after we had my dog put to sleep (I was 20 at the time, and I still cried like a little girl), it felt really wierd around the house. I ended up convincing my parents to let me take a friends dog (he was 4, now he is 7) who had bitten a child (the previous owner did day care) that followed him into his kennel. I was very close to this dog as well, since I was a friend of the family and had been playing with the dog since they had first gotten him. They either had to get rid of him or put him to sleep, and I wasn't going to let him be put to sleep ;-). I actually think it will help you get over your loss a lot more quickly if you get a new pet, but it really is your decision to make.
