Started feeding a confirmed stray a few mos ago. He was showing up when i left and when i got home religiously. Decided to “adopt” him, but wanted to take it slow for him. I put in a cat door that only goes to a small room in my house (i have another cat). He started coming in more frequently, stayed often when he was alone (have cam)and enjoyed my company too. I took him to vet to get shots and bloodwork. It seemed around this time he started to be more unpredictable when he would be there and with much less frequency. He now only comes to eat and quickly leaves. I hate the idea of forcing him in any way. What should I do? Should I get rid of cat door? I did put a Feliway diffuser out also around the time that i brought him back from vet, could that be having the wrong effect on him somehow? Trust broken? Another neighborhood sucker? this was at least 3 weeks ago. Any advice appreciated.
