Hi! First gratz on getting the pet token. I too have no interact option if i right click the actual pet.. I have to use the drop down box on the summoning icon and use the interact option that way. I have no idea why its like this because like you , with my alt, i can right click the pet and see interact. Hope this helps you.
The richest person is not who has the most. It is who Needs the least.
Look at your gameplay settings. There is an option called "Hide familiar options". It is the top right option in general gameplay. If this is checked, you will not see the interact option.
