Well, I have come to the decision to put Marco down. I will be making the phone call tomorrow morning..
Thanks to everyone on the Rat Shack Chat for putting up with my breakdown, as usual, over the scenario. Appreciated, as always!
As sad as I am, I am trying my best to keep a positive look on this. Marco has lived WELL past what was initially expected out of him...
(he is over 3 years old now, where I thought I was going to lose him about 1.5 years ago)
He has been a true fighter, thats for sure.
Unfortunately, old age has gotten to him enough now where I think it's no longer fair to keep him hanging around.
He rarely ever appears enthusiastic, his mobility has been shot, his weight is starting to fade once again, and to top it off, I discovered a testicular tumor on him this evening. I know surgery is going to be too tough on his body at this age (and condition), so I have decided to let him sleep and join his brother up there.
