We've lost two cats to forms of cancer. The more recent one was a good age for a cat, had always been nervous and was getting rheumatic. He developed a tumour behind his eye and there was nothing the vet could do except give him an injection - not sure, probably steroid. Anyway, we took him home and he had about 6 weeks of behaving like a kitten. Clearly he wasn't in pain from anything and was very content. As soon as he started looking poorly again we took him back to the vet and she put him to sleep. We were so glad that he'd spent that time really happily even though we were very sad to lose him.
Hope your little cat has a happy few weeks or months, seacliff.
