How wonderful that he found you!! I'm so glad that he is safe from your neighbour. Maybe he was all talk but it's not worth risking. What a relief that the rescue org you contacted will take care of all the expenses for getting him neutered, vaccinated and dewormed.
I hope he finds a good home but if he has to come back to your place at some point after he recovers, will your garage be available then?
That is neat that he has the same double toned purr as Puddy. Hmmm...
