This is sad ...

... Poor wee fellas.
I had some pet axolotls way back when I first left home. To make up for the loss of the family cats, dogs, birds ... they were not a very good substitute. I never quiet warmed to them, as I have done to fish. I've loved long and hard fish, wept over the death of fish, so it wasn't their non-furriness that was their downfall. I think it was that they appeared to be terribly, terribly stupid. They were very hard to feed and made a terrible mess of their tank.
In the end, my flatmate's cat got them out of the tank, in the night. I rescued them, revived and healed them, and gave them away to a bikie. They were a gift for his "lady wife".
