I can imagine how much you'd miss your cat. I once had a dog when I was a kid, it was poisoned by hating neighbours for reasons unknown.
It exhibited symptoms of poisoning the previous day and by the time I got back from school the next day my parents said they found its body opposite our compound- dead! It was buried before I got back.
I didn't cry but I felt pained since nothing could fill that void of losing a favourite pet.
