What would a bump the size of a small blueberry that frequently gets bigger and then gets smaller on a elderly cat be?

More than likely it is a benign cyst. Those are the type that become filled with fluid/water. If the cat is in good health otherwise there is nothing to be concerned about.

These type of cysts, sometimes enlarge enough to create problems for the animal, and then need to be drained or removed. * this can also occur with their lymphnoids Answer Of course consulting a vet for any reoccurring problem is always your best option: However in the meantime, Continue monitoring the cat for any other abnormal symptoms and/or unusual behavior... Give your vet as much to go on as possible. The more information the vet gets from you the more accurate the diagnosis.. in other words they will be able to more accurately tell you if the bump is indeed a benign cyst or swollen lymphnoid ANSWER: you might want to think:''is it a tick?'',and take you cat,and the bump(a.k.

A,do not skratch it of,yet)to the vet NOW. Thank you and good night.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
