Just seen ad for petting sloths I thought they didn't like being touched and it was painful for them if this is true they shouldn't be petted.

Very true👍🏻 these sloths are around people a whole lot more than ones found in nature... so they do not mind. You really just let them interact with you not the other way around...

Thanks for your concern Janice. We never force our sloths to do anything and they only interact with us when they choose to.
