I never tried that.
My gut reaction is it would be ok provided they were washed off first.
One or two of my Amazon’s would chew up the cobb to a pulpy mess.
MY baby ekkies love it . i read ekkies dont use there feet to eat . my femail does all the time my male tries but not good at it as yet . they are 14 months old .
As stated above, likely not a problem. That said and as stated above, washing is highly recommended as at least the outer couple of layers have /could have been dragged though most anything.
Having eaten the corn from the cob, the cob is a choice play 'thing.'
Our spoiled DYH 'kid' gets mad if his staff are not joy on the spot to turn his cob for him!
Seems to me, there's an awful lot of shredding toys made from dried, often colored husks. I have a few around. Typical of many toys, if my guys take a liking to one, it's destroyed in minutes. If they don't, it can sit forever until I rotate it out.
Amy loves 'em. I get a package of Birdseye mini corn cob and wash thoroughly. I heat one in the nuke machine for two minutes ( when they are still frozen) then cut the cob in half and make sure it's cool. He'll chow down the kernels then rip the cob to shreds. Ya it's messy but he enjoys it.
