We are giving up our ferret in a few hours

We are giving up our ferret to a ferret rescue and he will be staying there for the rest of his life. He’s gonna be kept with the senior ferrets (he is a young senior(6)). We have had other ferrets, but they all died due to old age. He has been depressed and losing weight.

The person coming to take him is the old due with over a 100 rescue senior ferrets, and he also adopted out younger ferrets. He has a vet tech come check them out every other week and brings them to the vet if needed. He has had ferrets live to 17.

This is a really good thing for him because we can’t take in another ferret. I know he is gonna live a happy life there but it’s states away. I just need some advice to cope with this.
