Heidi is completely healthy and has been spayed and vaccinated. As far as food , I may have someone who can donate a few big bags of science diet. I know its not the best, but its all I may be able to do.
The person I know also has a contact with a butcher and he said that I may be able to get animal parts, like livers, giblets, etc....I am a vegetarian so I am not sure what parts are not for human consumption...but he uses it for the colony he looks after and his cats seem to be healthy.
Anyway, let me know if you can use the food.
