I have a rabbit (age not sure .... Was found running free 4 years ago)

Customer Question

I have a rabbit (age not sure .... Was found running free 4 years ago) who has a pea sized cystic type mass on her underside.
It moves freely and does not seem fixed to her belly. Do I need to have it looked at, or aspirated?

Hello and welcome. The expert you originally requested is no longer available. Since the question was locked for her, no one else could respond until that lock expired.I apologize for the delay that caused. My name is ***** ***** I'm a biologist with over 40 years of experience raising and showing rabbits.
The answer to your question is that, yes, this lump should be checked out. It is growing, and while there are several possibilities for what it may be, if it is something troublesome, it will be easier to take care of while it is small.
Possibilities include a lipoma - a mass of fat - it would only be necessary to remove it if it is large enough to interfere with movement, or if it is pressing on organs. We can’t be sure this is a lipoma just by looking at it and feeling it. It may be a cancerous tumor. In that case, removal would be more complex, because tissue around it may also need to be taken. It could turn out to be inoperable, too. Or, there may need to be a follow-up of chemotherapy. The mass could also be a cyst, or pocket of infection, as you suspect. Rabbits are very prone to abscesses. Abscesses have to be drained, then followed with a course of antibiotics. If left alone, they can spread and even become systemic.
Because there is no way to determine what this lump is without a hands-on exam, it would be best to schedule an appointment with your vet. The vet can then determine if aspiration, watching and waiting, or some other procedure would be best for the circumstances.
