We've had Fred for 2 months and he's about 4 months old. Prior to him becoming sick he was really timid. He'd never run from us and would let us pet him and pick him up without hesitation but was still very much nervous. I could easily hand feed him and bathe him without any issues but again still adjusting to me. Well he got really sick 2 weeks ago and we took him to the vet and found out he had pinworms. Helping him get better involved force feeding a special diet as well as giving him medication for 5 days. Well now I'm the scary lady that makes him open his mouth and shove things inside it because anytime he sees me approach his cage he starts to get nervous. It's been a week since I've had to give him any medication and I'm still able to hand feed him but anytime I get remotely near him and try to pet him he opens his mouth and flares at me. He's not tried to bite or anything but obviously makes me a tad nervous he might. I'm not sure what approach I take because I don't want to stress him out and just never trust me but I also don't want to encourage the behavior either. I've been hand feeding him his fave which are silk worms and he takes them no problem but again doesn't want my hands on him. Thoughts? suggestions on what I need to be doing going forward so he forgives me and learns to trust me again.
