Hi my cat appeared to be suffering from arthritis so the vet did a blood test (under anaesthetic) and also on my request looked at teeth with a number being removed. An xray showed there was a mass behind his lung. we left with arthrocam and he had anti biotic injection. The blood test showed high white cell count which the vet said could be an infection. 5 days later I had to take him back and he was put under again - mouth infection was found which was cleaned and restitched.. I was given 10 days of Zodon antibiotic in liquid form. I managed 4 and half days but then was given tablets as he was refusing the liquid. In all this time he has spent most it under a bed. Appetite has not been good. Yesterday another visit to the vet as he was not eating. Given an antibiotic injection (apparently not as effective as Zodon) and an injection to encourage eating. He has eaten a bit but not a lot. He is still hiding under the bed. If the mass is causing this issue they need to put him out again to test the mass. I am reluctant to go ahead. He is 15 and half years old and being put under again is risky. I think it is maybe time to let him go - he is struggling to walk as well, possibly weakness. Does anybody have some wise words here - I am struggling to find a positive route through this. Sorry for length of message. Thanks
