My cat usually is very active, he is hyper, meows alot and purrs alot and usually all over you. Since Sunday he has been moping around the house, not meowed nor purred and he has a dry/warm nose???
I don't think the answer by sargeyla is good at all. Just because your cat could possibly be sick does not mean s/he is going to die. You don't give your cat's age. Do take the cat to the vet if s/he is not well in a day or two.
I'm sorry to say but I think your cat is going to..........die......because
everything you said about your cat acting strange seems to add up to just one thing but hey make sure with the doctor.
Cats are usually live up to 14 but like nobody knows when people are going to meet their end anyways best of lucks!!!!!
Tell me if anything serious happens!
