A cat and dog that once kept their distance are now spending more time together, but while their owner saw it as a sign of bonding, a veterinarian said the behavior may not mean what it seems.
Pet parent Liz told Newsweek her orange cat, Kitty, and Lemon, the golden retriever, did not always have a close relationship. When Lemon first came into the picture, Kitty would avoid the dog whenever she got too close, despite being a naturally affectionate cat with her humans.
Over time, however, their dynamic began to change. Kitty started allowing Lemon to approach, tolerating gentle interactions and even choosing to nap near the dog. Liz recently noticed the pair “birdwatching” together outside, with Lemon getting into the hobby to bond with Kitty.
While the birdwatching bonding moment looked like a clear friendship forming for Liz, Dr. Susanne Heartsill, veterinarian and U.S. director at Ceva Animal Health, told Newsweek that appearances like this can be misleading.
Instead, cat-dog bonds are often built in quieter, less obvious ways. She highlighted four surprising ways those relationships actually develop.
1. Focus on ‘Shared Wins,’ Not Shared Play
Many owners assume cats and dogs bond by playing together, cuddling or constantly interacting, but one of the most effective strategies to encourage a positive relationship may involve rewarding calm behavior.
For example, a dog calmly looking at a cat without chasing or a feline remaining relaxed while a dog is nearby are moments worth rewarding.
“Rather than focusing on direct interaction, have the cat and dog enjoy something rewarding at the same time while remaining comfortable and relaxed,” Heartsill said.
She recommends activities such as treats, training sessions or playing in the same room, as long as they do not trigger resource guarding or stress. Over time, both can begin associating the other’s presence with positive experiences. These are “shared wins.”
“The strongest cat-dog friendships often develop not from playing together, but from repeatedly experiencing good things in each other’s presence,” Heartsill added.
2. Let Cats Observe From Above
Giving cats control over distance can make a relationship between cats and dogs more likely to succeed.
Cats often feel more secure when they can observe dogs from elevated spaces, such as cat trees or shelves. Allowing them this distance can help felines feel more comfortable in a dog’s presence.
“When cats feel in control of distance and access, they’re more likely to choose proximity voluntarily,” Heartsill said.
That choice matters in building a bond. A cat that can retreat when needed is more likely to gradually become comfortable approaching a dog on its own terms.
3. Peaceful Indifference Is Progress
While many owners expect affection or play as signs of bonding, experts say early success often looks much quieter.
“Success isn’t necessarily play or affection—it’s calm neutrality,” she said.
A cat and dog that can share a room, move around each other without tension and relax in the same environment are already showing important signs that the relationship is developing well.
In fact, peacefully ignoring each other can be the first step toward a stronger bond.
4. Don’t Mistake Shared Activities for Friendship
Moments of cats and dogs appearing to “do things together,” such as bird watching side-by-side, are often interpreted as evidence of friendship, but Heartsill cautioned that the shared attention does not always mean social connection.
Both animals may simply be responding independently to the same stimulus, driven by curiosity or instinct rather than interaction.
“It’s important to avoid anthropomorphizing animal behavior,” Heartsill said.
A cat and dog watching the same thing may look like they are sharing an experience, but the behavior could simply reflect parallel instincts rather than a developing bond.
Building a Bond Takes Time
One of the biggest mistakes owners make when introducing cats and dogs is moving too quickly.
There is no universal timeline for when these animals should become comfortable with each other. Heartsill said some animals adjust within days, while others may need weeks or months. Not every relationship will look the same.
Heartsill said owners should focus less on the amount of time that has passed, and more on their pets’ body language, moving forward only when both animals appear calm and relaxed.
“Successful integration is less about forcing a relationship and more about providing structure, safety and choice,” she said.
