Agoutis have great adaptations and they will not have to change anything except thinner fur. They are fast runners, good swimmers, can burrow, have a good jump, and are nocturnal. With them being fast runners they can get away from their predators quickly and get where they need to. Being good swimmers can help if the world got flooded, they could just swim where they needed to go. Agoutis can burrow, and that can help by giving them a home and place to sleep. Agoutis can jump up to six feet which could also help escape predators. Being nocturnal can help if they need to go get food or just need to be out, they could see their prey and predators. In 1,000 years I think they will have to eat insects and grass because I dont think a grassland is going to have fallen fruit.
