Your cat's private file and first responder: logs food, litter, weight, meds and moods, preps vet visits, and in a scare tells you plainly when to go now.
Your dog's private file and first responder: records, meds, vaccines and vet visits, sitter sheets and lost-dog kits, and plain advice on when to see a vet now.
Your private pet desk: a file and log for each animal, a new-pet first-weeks list, vet visit briefs and after-visit notes, and a food and preventives list.
