Is it okay to feel attached to a virtual pet?

Yes. People have cared about virtual pets since the Tamagotchi in 1996, and feeling fond of something you look after every day is ordinary, not a sign that something is wrong. Research on AI companions finds that feeling heard can ease loneliness for a while, and that very heavy use goes with more loneliness and dependence. A good rule of thumb: the attachment is healthy when it adds to your life and nudges you toward people and the world, and worth a second look when it replaces them.

Why it happens

What the research says

Feeling heard helpsStudies of AI companions found that conversations reduced loneliness in the short term, mainly because people felt heard (De Freitas et al.).
Heavy use is a warning signIn a four-week study with 981 people, those who used a chatbot the most reported more loneliness and more emotional dependence (Fang et al. 2025).
People help moreShort, friendly phone calls from people cut loneliness noticeably in a randomised trial (Kahlon et al. 2021). A virtual pet is best as a bridge to people, not a stand-in.
Sudden changes hurtWhen companion apps changed their characters or shut down, users described real grief. Your feelings in that situation are valid too.

Healthy, or worth a second look?

Usually healthyA few minutes a day; it makes you smile; it reminds you to drink water, go outside or text a friend; you can skip a day without distress.
Worth a second lookYou cancel plans to stay with it; you feel panic or shame when you miss a day; you spend money you can't spare on it; it's the only one you talk to about how you feel.

If you recognise the second row, nothing is wrong with you; it's a sign to add a little more of something else. Tell one person how you're doing this week, or look at small ways to feel less lonely.

What to look for in a virtual pet

We compare a few with these rules in virtual pet apps for adults with anxiety.

If you're going through something heavy, a pet can't hold that for you. Please talk to a person: 988 in the US and Canada, Samaritans on 116 123 in the UK and Ireland, or findahelpline.com elsewhere.

We built Nuku with these rules: it never dies, there are no streaks, it says it's an AI, it gets sleepy after a long chat and asks about the people in your life. Nuku is a tiny AI pet you visit for about thirty seconds a day in your browser. If you stop visiting for two days (you choose 24 to 72 hours), it sends one notification to up to five people you picked. It's free, 18+, and not an emergency service.

Questions

Is it weird to love a virtual pet?

No. Caring about something you look after every day is a normal human response, and millions of adults play virtual pet games. It only deserves attention if it starts pushing out people, sleep or things you used to enjoy.

Can a virtual pet help with loneliness?

It can make some moments feel less lonely, especially when it notices you or nudges you to reach out to people. Research on AI companions suggests the relief is real but short-term, and that people, even brief phone calls, help more.

Is it normal to feel sad when a virtual pet app shuts down?

Yes. People have described real grief when companion apps changed or closed. The bond was real to you, so the loss is too. Talking about it with someone helps.

How much time with a virtual pet is too much?

There's no fixed number. A useful check is whether it adds to your day or replaces things: if you're skipping sleep, plans or people for it, cut back. Good pet games are designed for short visits.

Should I talk to an AI pet about my feelings?

Light things, sure. For anything heavy, talk to a person you trust or a helpline. An AI pet isn't a counsellor, and a good one will tell you so and point you to people.
