I think pet sites that offer daily features where users can collect items or earn rewards are great for encouraging repeat visits. Neopets, Subeta, Marapets, and Flight Rising all incorporate these types of features effectively.

Games also help retain users by keeping them engaged. Some players enjoy earning points through gameplay, so having a mix of luck-based and arcade-style games is a good strategy.

Quests are another essential feature, as they contribute to the in-game economy and encourage users to return for rewards and currency. It’s a good idea to offer multiple quest options to prevent boredom and allow players to use different methods to earn points.

A battling system can also increase engagement, especially if there are worthwhile rewards and a well-designed training system. Many players enjoy training and battling with their pets, making it a valuable feature.

A school or training system can further enhance daily visits, as some players enjoy improving their pets’ stats. This can serve as a core daily activity that keeps members returning to the game.
 
Regular rewards, activities, and pet character development are the important features that can make the players devoted to the site and they’ll keep coming back.
 
I think that understanding the core essence of why those old users loved your site at the first instance would help here. With that, you would know the features that you should add to the pet site as new features and updates to bring them back. Look at what Neopets is doing with attracting back the old users.

That is perfectly correct, understanding why your users stick with the site would form the foundation on how to make them return back to your site. So, mixing up nostalgia with the modern mechanics will improve player experience and they will likely check back.

Exactly. Nostalgia mixed with fresh updates is what keeps players hooked. I used to return to a site just because they added small new features every few weeks. It made it feel alive.
 
I come back when the game gives me something to look forward to without feeling like a chore. Small daily rewards, events, or progress that feels meaningful keep me engaged. I also return more when my pet feels unique and my actions actually matter. I think you should remember these things while designing your pet site.
 
You don’t get returning users just by adding features, you need to give them reasons to come back regularly. Daily systems like small rewards, tasks, or check-ins that feel worth it.
Events and limited-time content create urgency, while community features like trading or chatting give social reasons to return.
