They also are likely to reach thru the grate to try to get food dropped from earlier feedings that is now sitting in the waste. A swing, several sizes of perches, and a nest of some sort should be provided. They are fairly inexpensive to have made and well worth it. Some hardware stores will sell and cut plexiglass pieces to size. They can be secured to the insides of the cage with brackets, but any nuts and washers put on screws should be facing outside to prevent the Lory from removing it, and they will if they possibly can.
Lories love to play and wrestle so they tend to be rough with their toys.
Toys meant for larger birds are good. Toys meant for parakeets are usually not strong enough. Bells at the end of rawhide are among my Lories favorites as well as balls with bells in them found in the cat section of any pet store. Because Lories will spend most of their day playing, they can become bored with their toys easily, so it is best to have plenty of extra different kinds of toys to rotate from time to time. If you have any additional questions, I will be happy to try to answer them for you.
