I had little Boo for almost 4 years. Within the last couple of weeks, he had to overcome "swimmer's bladder" and then "dropsy". Although he did not look like his normal beautiful colorful self, I thought he would, somehow, recovery. But he did not look good(he looked very pale and bloated and had trouble eating/catching his food, he had to lay against the bowl, etc). I made the very painful decision, yesterday, to euthanize him(clove oil and volka). It has been 24hrs and I still keep crying. I can't believe he is gone. I gave him a "proper burial"(I carefully wrapped in up, then put him a ziplock bag and placed him in my freezer, in his favorite temporary "water changing" plastic bowl). I miss him!! R.I.P. little Boo!
