I think they will be fine, Gucci has eaten a number of things

the lil stinker and so far he has been OK with either passing them or vomiting them up. I hate when he does either but I'd rather it come out then poke something internally or become a blockage.
The largest thing was a Nose from a Stuffy about the size of a Penny and round and fat! I don't know how he vomited that up but he did

it was very scary to see that come out of him. I was so thankful it came out ok.
I am glad to hear they didn't chew the entire thing up and only got pieces of it.. I think they will be OK.
Please do keep us updated on how they do. It usually takes Gucci 24 hours for things to come out.. so not the first poo after the ingestion but the second one it should be there.. Hope that helps!!
