Hi Everyone - Well I phoned the vet this morning AND spoke to a vet nurse who gave me lots of advice.
She said that as her eyes / nose were clear and shes eating well and lively then its most likely a fur ball in her stomach or a scratch to her throat.
She said to get her some malt paste to try and shift it, and brush her as twice a day and keep a close eye on her.

She said if anythign changes with her then to take her in but for now treat it as a scratch or hair ball.

Lets hope the maltpaste works...
