Not to freak you out.
We woke up a few weeks ago. Noticed a lump on the side of one of my Carpets. Wasn't there the week before. Took her to the vet and got X-rays. Turned out to be cancer. She made it another 2 weeks.
I would get her checked out for sure.
Good luck
No idea how long. It was just noticed last night.
I'm going to get her into a vet then. I hope this isn't cancer.
