A newly adopted pair of cat sisters have melted hearts on social media after a heartwarming video of their first week in their new home went viral.

The clip shared on TikTok on Saturday, under the username @lillylucysisters, shows the two tabby cats, Lilly and Lucy, curled up in their owner’s arms, purring with joy as they nap there together.

“Imagine adopting two rescue sister cats… and this happens in the very first week. Can you imagine what my heart feels like?” reads layover text in the clip. And a caption says: “My heart was exploding.”

Adopting two cats from the same litter is a big decision that can go either way. They can provide each other with companionship and prevent loneliness, though this depends on their individual personality.

A Catster article, medically reviewed by Dr. Maja Platisa, explains that kittens from around three to four weeks of age tend to get along up until they reach social maturity, between two and five years, after that things can change.

Sister cats may bond closely or prefer solitude, with some engaging in cuddling and grooming, and others merely tolerating each other. Brother cats often compete for leadership. They can either become inseparable or have endless conflicts.

The advantages of adopting two kittens from the same litter include having constant companionship, entertainment, warmth, and grooming, but most importantly always having a play mate by their side.

To keep tension between them at bay, make sure they each have their own litter-boxes, and food and water bowls. You can also use pheromones to make the atmosphere in the house more chilled for them.

The video quickly went viral on TikTok and it has so far received over 5.9 million views and 1.6 million views on the platform.

One user, XENA, said: “Can you imagine what my heart feels like watching this with a cat who hates physical touch?! JEALOUS.”

Rachcondi added: “This is all I want from my non affectionate cat but she looks at me like she is plotting my death.”
