I moved out on June 3rd and unfortunately couldn't take Felix with me. I left him in the care of my mother. I haven't interacted with him much since I moved out until this week Tuesday and today. He is acting strangely towards me. On Tuesday, he looked at me scared so I stretched my hand out for him to sniff it (because that usually calms him down when he's not sure who it is) and he was rubbing on me for a little bit but then he suddenly got upset and hissed softly at me and slapped me. It wasn't a hard slap. His claws were not out or anything and there was no growling. Then, he rubbed on me again and then continued with the hissing and slapping. Has he forgotten who I am because I haven't seen him in some months? Today, he was more calm around me and came out for me to pet him (he didn't on Tuesday). We were having a good time and then he went back to hissing softly and slapping me, no claws. He did bite me but it wasn't hard bites. I'm not sure what's going on here...
