Hi as you can see from the attached photo, my cat has a soft-ish lump on her back. It's white with some visible veins on it. I just wanna know if its potentially dangerous or not? (Ive been poking the lump and she is not in any pain whatsoever)

Unfortunately in a cat Toy's age, there's a chance any lump could be malignant. It could also be benign or a cyst. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. I'd take her into a vet today to get this checked out. Best of luck.
