You've been a member here since August, and have had 4 chinchilla deaths that you've posted about in the memorial section. In such a short time frame with a small number of chins, that is a lot of deaths and is usually an indication that there is something going on, be it in your husbandry or your care of the animals.
Also, Cassi has a point in the fact you should have gotten your chinchilla to the vet, regardless of whether there was an exotic on or not. Any one of them could have called the exotic vet to see if he'd come in, or if nothing else could have put the chinchilla humanely to sleep without having him suffer. If you, are your parents, are unwilling to take an animal to where it can get the help it needs when it needs it, you need to re-evaluate having chins in general. There are some things that can potentially be treated at home or with the help of a mentor, but when you have an established breeder who has dealt with more than her share of issues telling you to get to the vet, you should have been in the car, going, even if it meant he passed while in the car. At least you would have been making an attempt.
