I'm so glad you're seeing progress.
With Echo most of the time there was no 'cause' no food or toys or even people, simply out
of the blue she would launch into Darwin.
Echo was the problem, but we couldn't rehome her or find a rescue.
Why ???
because everyone else would have the same problem.
It took us 6 weeks to get her to trust us enough to let us touch her.
She would have been put down.
We had to persevere.
3 years, and finally. Peace.
I'm not saying she'll never have a go at him again.
But hopefully, it'll be a rare occurrence.
