Can you tell me your kitty's symptoms?
Did the vet diagnose a blocked salivary gland?
Where is the blockage located?
Thank you for the additional information. Unfortunately, there really is no other treatment for this condition. The blocked salivary duct (salivary mucocele) can only be corrected with surgery. Simply draining it will not keep it away. It will continue to fill back up. Your boy is getting on in years, but if the mucocele is getting so large that it is causing him to have trouble eating, it is something that should be taken care of. If your vet is not comfortable anesthetizing your boy due to his age, he should refer you to a specialist. There are definitely risks to older animals that go under general anesthesia, but if they are monitored closely, they will usually do quite well. I hope this helps. Please reply if you have further questions about this.
