New here, and the tutorial abandoned me. Is there a less drawn-out way of feeding and playing with your pets? Rather than going inventory-->item option screen-->item use confirmed screen-->back to inventory, repeat at least twenty times for each pet? It's. Ah. Kinda tedious. Particularly when you have to do pretty much the same thing to buy the items if you don't have them.
You can just check them into the Resort in Veta Lake
Unfortunately, no. Although if you just want them to be fed and happy and you don't care about feeding them specific items, you can always put them in the resort in Veta or Rathskeller Inn if you have access to the Omen Islands. The price per day is the same for each place, and it will keep your pet happy and not hungry for the duration of their stay.
You should also be aware that you don't /have/ to feed and play with your pets - they can stay at 0 hunger and happiness forever with no adverse consequences. However, if you want to battle with your pet they have to have at least 1 hunger and happiness when starting a battle.
