After a complete examination, a vet revealed that it is believed a severe head injury may have caused his eyes to pop out.

Despite their very best efforts, they added that the little kitten will need both eyes removed.

Earlier this week, the RSPCA put out an appeal in a bid to try and raise £1,000, ($1,318), to pay for the operation and fund ongoing care.

So far, more than that original goal has been donated.

Kerry Draper, who runs a rehoming centre, stated: ‘Sadly, it's unclear how Rupert sustained such injuries but it was immediately obvious that he needed specialist care to provide him with any chance of recovery.
