The nine week old kitten had to have its eye removed after it was abandoned outside an animal hospital in the the dead of night.
How the cat was left with its eye bloody and bulging out of the socket is unknown, but staff at the South Essex Wildlife Hospital say it should have been treated with more dignity and compassion.
A receptionist found the kitten in a box next to the hospital’s front gates in the run up to Christmas.
She was so badly injured that vets had to remove her left eye.
Outlining their disgust over the way the kitten had been abandoned, the the wildlife hospital near Grays, Essex, released a picture of the kitten on social media and told supporters: “This does make us a bit cross.
“If you want to get rid of your pet, for whatever reason, please don’t leave it in a box outside our gate in the middle of the night.
“Please have the compassion and common sense just to phone.”
The kitten is recovering slowly and there are already plans for her be to given a safe indoor home once she has recovered.
Set up in 1995, the animal hospital charity looks after a wide array of native British wildlife.
Its address is not published and whoever left the kitten outdoors at night was putting its life in danger.
A spokesman said: “Leaving animals outside in the cold is a risk.
“They could succumb to the cold rather than their injuries so it just reduces their chances of survival greatly.
“We do not commonly have animals waiting for us because we do not publish our address.”
How the kitten was left with an injured eye remains a mystery.
The spokesman added: “It is awful really what has happened to the poor thing.
“We do not know exactly what happened to it – it is better we do know their history so we can make sure we know how to care for it.
“People get their cats caught in places, they may run out and get hit by a car or they discover an injured animal.”
