A little roo we rescued from our neighbors about 2 months ago is sick. He has a big lump on the side of his neck and has been sleeping constantly not moving much. He also has been itching it a tun. We would like to check it out but since he was abused before he doesn't want people near him. He is so sweet but not trusting. And we don't want to stress him by picking him up and messing with him ya know what I'm saying? We think it's an infection but not sure. Please tell me what y'all think cause he's getting worse by the hour. Thank you.
