Bump?

IS it normal for a cat to have a bump,real small right where her back and neck almost connect? Thx

I dont feel that on my Cats. Has the Cat has any Shots there? Coco has a lump from her Depo Shot last week.

Does it feel hard like a bone? Is it near the shoulder blades? I've been able to feel some of my cat's microchips in the area between their shoulder blades and along their spine (except Zek's, since his migrated to his right elbow area). If this is something new, I would get it checked out.
