I'd be nervous about it causing a blockage (if ingested). Maybe its like with wood, they chew it but don't eat it, but I wouldn't try it. There are a lot of toys out there that aren't really all that safe.
I would be cautious. if you look at some of the toys for sale they are made of foam.. i tried to find out whatkind of foam... maybe a difference.... not sure.... I am not an expert in this . so I would be very careful..............

Isn't that the truth!!! Its make me wonder when I see bird toys with cheap bells that the finish is flaking off. Or my favorite the toys that say 100% bird safe and its got a zinc coated quick link.
