Sorry, slightly disgusting vomit question

[berties mum]

My neighbour said it sounded like bile too, BC.  She's not eaten any treats since Christmas Day, but she does go outside so I don't know what else she's eaten.

If it is bright yellow it sounds like bile from her liver, perhaps too much fatty food ove christmas?

[berties mum]

She's roughly seven, eight at the most.  I wondered whether she'd eaten something gross outside ...

How old is she? I wouldn't say normal, and worth asking your vet about.

Woke up this morning to find Minnie curled up on the floor at the end of the bed, which seemed odd until I realised she'd been sick on her blanket on the end of the bed so decided to shift onto the floor    I was a bit taken aback by the colour of what she'd thrown up - it was bright yellow, a really livid colour.  Sorry to ask such a disgustin question, but is this normal?  Bella never seems to throw up, but when Bertie does, it's always regurgitated food so it's brown, or green if he's eaten a houseplant    But I've never seen anything yellow before.  Minnie is absolutely fine in herself, eaten like a horse as usual today and now sleeping on a fresh blanket at the end of the bed!
