I have two black and white or white and black kittens, two black (tiny bits of white if you look for it, not much), had both lots of vaccinations, have come on leaps and bounds from hiding in the corner.
I have a ginger long haired female and a white and ginger female, plus a black semi long haired boy (OH keeps calling him "Sticky Paws" because he thinks he will stay!). The first two of these three are still in quarantine, and the black boy is getting over a virus, which I think he has managed to share with the others in some cases, even the old boy called Sylvester who is 15, seems to give them a temperature, sore throat in Sylvester's case, he did that swallowing thing when you showed him food, although he did not give up eating completely and gooey eyes.
One of the black ones seems to have a sticky eye, and so does one of the black and white ones today. It is probably because although, "Sticky Paws" seemed better, and even had his first vaccination, I put him in the pen with the others and he may have still been slightly carrying the original virus he brought in.
Again that was due to lack of space, I had to put a cat with a life changing injury in his pen (which we had to Virkon first)the other night before we took her to the vets first thing in the morning. It was an old injury, and there was spinal damage to three vertebrae, and the vet gave her a thorough examination, which included taking x-rays. Sadly later he rang me with the information that we didn't want to hear, that she had no prospect of a good quality of life and if it was his cat he would let her go. So sadly we had to agree with his decision, and she was released from her discomfort whilst she was still under sedation.
