My biggest problem is that you say the litter was an accident.
Did you not put the male and female together, but later decide you didn't want to breed, but it was already too late?
If so, it is not an accidental litter.
And really, until you have true rescues in your facility you cannot vouch on how they are treated. You really should explain that you are just starting and no rats have been surrendered to you. You can say that you intend to treat them and spoil them. But until you have them, you cannot talk about what you do.
And instead of copying information from links, why not list the links on your website. If anything, it would lead them to finding more information because those sites have links, and their links have links on them, etc etc.
As far as bedding.. CareFresh is better to use than what you had your babies on (pine), even if you put them in it temporarily for a photo. It may confuse people when they see you using pine in your pictures, but saying you shouldn't use it at all on your info page.
When talking about bedding, you should confine your opinion in the "Rats Dos and Donts" to your experience with Carefresh and your rats, not other animals. And Cedar causes the same problems as pine and both can cause respiratory infections, scaring, difficulty breathing, etc. What type of wood do you mean when you say "Large Wood Chips?" You should specify because they might think you mean cedar wood chips instead of shaved cedar, which can be dusty.
And the Snak Shack you have listed isn't good for rats at all. It contains things that can be harmful to rats, like pine and cedar. It also is open to the air of the entire petstore and you could carry home SDA with one of those. Because they have some moisture to them, it is safe to say that germs and bacteria aren't just on the surface, but can burrow inside. Not to mention they contain alfalfa which is indegestible to rats.
As a rescuer myself, I will tell you. Your heart will be broken, your efforts degraded by irresponsible people. You'll lose money, not make it. Don't expect people to donate huge amounts of money or items like cages. RRR has not recieved one single donation in over a year and a half until Sunday. We recieved several free hammocks from myzoo2, on GooseMoose for buying a cage from her and for having rescues at the time. It was our first ever donation.
