It was on Mon 1/31. It is still hard for me to realize he is gone. He had a lot of health issues, and enlarged heart and a heart murmur, very enlarged liver and possible kidney problems. The hardest thing is Chante is really missing him and has not been his usual active self and is eating very little. I am taking Chante in to the vet for a check up just to make sure nothing else is wrong with him. Unfortunately Nick is pretty much a loner but I may be adopting another male blue head in a week, I am going to meet him tomorrow and I hope he will be friends with Chante
