MY CAT JUST DIED :'(?

I feel very sorry for your loss and I know what you are going thru. I have 9 cats now but before these 9, I had 7 cats and they all died within 3 years. The oldest one lived to be 19. Its hard to get over the loss of a pet. I'm sure your cat knew you loved him. Don't beat yourself up over these losses. They say time heals but I still think of my cats all the time that aren't with me anymore. I know they say death comes in 3's and its a scary thought but try not to think about it. Your cat may have had something wrong with it that you weren't aware of. The same thing goes for your puppy. The best thing I can tell you is to make sure your animals are checked by a vet for diseases that can be spread to other animals. As far as getting over the loss of your cat, it is going to take time. It does get easier but it takes a while and its not easy.
