Questions after death...

Question:
 Hello all. I am new to this site, and normally don't post on these things, but I am mourning the loss of one of our cats. Sadie was a tiny black short hair with yellow green eyes, and had the sweetest personality. She loved to cuddle with us, or her litter mate (brother) Bailey (an orange and white, tiger-striped, short hair) who grew to be twice her size. The two of them were inseperable most of the time (unless Bailey became too aggressive and ran Sadie off). The two of them were a Christmas gift from the end of 05', which had easily been the darkest year of my life, having lost my Dad the beginning of that year. They've brought so much joy to the both of us since they were adopted. I don't want to make this sad story too long, so I'll just tell you that going to bed this past Friday night Sadie was her usual self (cuddly, affectionate, full of energy)...the next morning she's under our bed (not moving, and stiff as a board...she had passed away sometime during the night). The vet checked her out on Saturday, and concluded that Sadie had some kind of heart disease that she was most likely born with. Nothing that anyone could have diagnosed, and she certainly never acted sick around us. She never really ate alot, and occassionally her breathing wasn't always clear (two signs that we now know were attributed to the heart problems)>. You can imagine our shock, horror, emptiness that we're feeling now. We've had no motivation to do anything all weekend, due to the heartache. We both miss the little girl, and Bailey has actually been the one that has been handling it the best. He sniffs around alot (picking up her scent) and looks around for her from time to time (even after we showed him her body), but he's hanging in there. My only worry is going back to work this week, and he's suddenly alone in the house by himself. Have any of you gone through this before? I'd like to get him a new companion one day, but how soon is too soon. We've both lost pets before, but nothing this sudden. Of course nothing will compare to the pain of losing my Dad, but this will definitely hurt for a little while. Any thoughts or advice on dealing with this situation are much appreciated. Thank you!
Answer:
 I'm so sorry for your loss. I'm sorry but I don't know what to tell you. He probably understands what happened since you showed him the body. It will just take time for him to adjust. Just give him all the attention you can.
Answer:
 Sorry about your loss. After our male cat Corkins died our female cat Lexi continued to look for him for quite awhile. He was hit by a truck and we wrapped him up in a towel and took him in the house right before we rushed him to the vet and Lexi saw him then and knew he was hurt so she probably knew what happened when he didn't come home. She did keep looking for him a little bit but otherwise she was fine. We got 2 new kittens a couple months later and she was fine. We knew she was lonely without Corkins as they grew up together so she was happy to have playmates again. She was less than a year old so she was still a bit of a kitten herself. We miss him so much so we made a collage of pictures of him from kittenhood to just before he died and framed it and hung it on our wall. It's really nice to have his pictures around. Something like that might help you to deal with the pain of losing Sadie. Hope my story helps you.
