So the real fluffy tail has been an indoors cat since we adopted her. She has never been a lap cat, preferring to observe us from afar. She's always been particular about food, eating 2 pouches a day and not really that bothered about human food. We were told she's been spayed. We recently moved to a house with a cat flap and she's loved going outside.
All of a sudden though she's obsessed with food, eating everything in sight. She's also started sitting on our laps for hours, purring away. During one of these times I found a hard lump in her fur. On closer inspection it was one of her nipples which appeared much bigger than usual. She's also got noticeably fatter around the belly.
Any suggestions about what's going on?
