Companion pets are the emotional and functional heart of Heartopia. Beyond following you through the meadows and snuggling on your home rug, well-cared-for cats and dogs unlock passive overworld foraging perks, assist with livestock management in your Ranch, and can eventually compete in weekend Pet Racing Competitions.

This foundational guide covers the complete pet adoption process: veterinarian Oak-Oak’s questline, dog and cat breed specializations, daily grooming rhythms, home enclosures, and companion affinity ladders.

Daily Care Rhythms: Mood & Affection Mechanics

Your companion’s happiness is tracked through their Affection Gauge (0 to 100 Hearts). Maintaining their mood in the Ecstatic Zone unlocks their active helper perks:

[Melancholy: 0-25] ➔ [Content: 26-60] ➔ [Happy: 61-85] ➔ [Ecstatic: 86-100]
     (No perks)         (Follows you)     (+10% helper odds)    (Full perks active)

1. Feeding Requirements

Daily Chow: Fill their pet bowl once every 24 real-world hours (resets at 06:00 AM server time). Basic Pet Chow restores 20 Affection.
Gourmet Treats: Feeding your cat Grilled Salmon or your dog Honey Roast Chicken (from your Cooking Station) restores 40 Affection and grants a temporary 2-hour sparkle aura.

2. Grooming & Hygiene

Equip the Soft Bristle Brush and interact with your pet. Complete the 3-stroke circular grooming gesture to remove tangled burrs (+15 Affection).
Bathing: After rainy days or muddy foraging runs, wash your pet at the Wooden Wash Tub to keep their coat cleanliness meter maxed out.

3. Playtime & Interactive Toys

Spend 2 minutes daily throwing balls for dogs or waving feather teasers for cats.
Once your pet reaches Friendship Level 3, you can transition into advanced stat conditioning using our Pet Training & Toys Guide.

Pro Caretaker Tips & Synergies

Companion Swapping for Daily Roles: When heading out on deep-ocean fishing expeditions, bring your Calico Cat for the rare catch bonus. When surveying new mountain paths for buried treasure, switch to your Golden Retriever.
Weather Shelter Protocol: During severe storms, recall outdoor pets inside your home plot using the pet whistle to prevent their mood from dipping into Melancholy. See our Weather System Guide for storm schedules.
Prepare for Weekend Races: Daily affection maintenance is a prerequisite for competitive racing. A pet at 100% Affection gains a +10% acceleration boost out of the starting gate in Pet Racing Competitions.
