I was stroking my lovely rescue cat earlier and felt a lump about halfway up her tail. It isn’t visible as it’s underneath her fur, but I could clearly feel it when stroking her. The lump is probably about 0.5cm long and is firm and hard. When I pressed on it she flinched and mewed.
I’m obviously going out of my mind with worry and will call the vet first thing tomorrow, but in the meantime, does anyone have any idea what it could be? She’s only three years old and seems perfectly fine and happy within herself. Thank you
