Poor, poor Jasper!! Oh I'm so sorry. Sending you both lots of prayers and positive vibes.

When did the doctor say they could find out more about the tumor?

From what I read before sounds like the doctor in your place is not the most advanced and you would have to take Jasper somewhere else for a thorough examination. I know it would be costly, but I'm sure whatever vet you chose would work with you on a payment plan. I'm trying to think of other options too.

I'm so sorry for your stress and worry. I can't imagine how you feel right now. Try to keep your chin up until you know for sure what is going on. Hopefully the tumor is not cancerous.
