My cat is getting older. He is about 11-12 years old. He has devloped two lumps on him. What could this be?

Hi, kiterunner!

Where are the lumps on him, please? Also, is he in pain because of the lumps?

Some educated guesses might prove to be of value here. Although, you do realize, that the best that we can do here is guess. To really know for sure, it would be best to take him to the vet.

Thanks!

They could be tumors, or cysts, or something entirely different. Only a vet can tell you for sure.

The lumps are on his side... kind of on the side of his leg. I don't think they are anything harmful because he has had them for awhile now... they almost seem like cysts.

Has a vet taken a look at them? Like I said, they could be anything. Only a vet can really tell you.

No, I need to take him asap I suppose

Yes, you do. You don't want to assume they're cysts just to find out they're tumors that need removed.

Yes, he has an apt this week with the vet :)

Good. While it's likely that they're harmless, it's always better to be safe than sorry when dealing with health issues.

What's the other options? Does anyone know.. because my cat has a lump on the left side next to spine by his back leg :(

As I said before, only a vet can tell for sure.
