big.
a lori cage must be at least 3ft high if not more; 2 ft deep. bigger is better.
and you must let it out all the time and socialise it more than you would your child, lol.
if not all you will have is an upset, loud and unpleasant bird around the house.
toys should ideally be shuffled around especially if you are not there during the day, and you should get mentally stimulating toys. mirrors are a big no no with any bird.
hope that helps yuna.
