My cat

My cat has recently in the past few months been throwing up alot and losing weight. I cant figure out what it could be. I have tried other foods and nothing is helping. Its so much to take him to the vet and i will if i need to but just was curios if anyone had any idea of what could be happening.

You can try to dewormer your cat, but if it doesn't work you'll have to take your cat in to the vet. It's likely a parasite, and some of them need medication you can only obtain from your vet. Even an inside cat can pick up a parasitical infection.
