Okay, here's the update on my cat's condition. We brought him to the vet today, and the vet said that it was probably caused by some fight with another cat. The big bump that he had there had popped, and blood had come out of it, and it was really gross. So he's gonna be fine, thank God, and I only have to give him some medication for 10 days. I also found out that he only ways 9 pounds. I've had my cat for over 8 years and he only weighs 9 pounds. I thought that was a little weird, but as long as he's gonna be okay, I'm happy!:)
