Thanks for the thoughts. I hope one response will do. As originally noted, the list is directed at our potential clients.
Martin cages: agreed that some are pretty good. We have one listed. As to food, we feed Oxbow so all chins being adopted are on it. We give info on mazuri. They are the only 2 good foods in our area. Oxbow is by far the most readily available. Petco and PetsMart both sell chins in NOLA. We would rather not patronize them.
Wheels: Of the three common wheels: QC, Eds, Carisse's, only the QC is worth the client's money. We have some of all 3. The QC's bearing problems are very few, they will be corrected with a phone call, and they should become a moot point soon with the new sealed bearings. The Ed wheel is smaller and costs more. The rescue wheel has limitations that make it not the best wheel for a household pet although it is much better than nothing in a rescue setting. If money is that much of an object, they won't be adopting from us anyway.
Saucers: experiences vary widely. If I knew a particular chin would be happy with a saucer there would be no problem but to date, most of those surrendered do not even have a wheel. All our chins can and do run on wheels. Adopters will still need to provide a chinspin wheel to adopt. It is no problem to add a link though.
As to treats and safe chews, people usually check out this page after reading Kara's Petchinchillas.info pages. Mine was kind of designed to be a companion piece to hers, but with a more local scope.
Again, thanks for the thoughts. I can see it is still a work in progress.
