Many people are obsessed with Diet Coke.

Heck, this year Target put an entire clothing line devoted to the love of this drink, known fondly as the “fridge cigarette.”

But what about our pets?

Well, it turns out in this funny pet video, there’s a white cat obsessed with Diet Coke, and it’s completely relatable.

Feta loves a Diet Coke as much as the rest of us, it turns out.

Why Cats Are Curious About What We Drink

Feta was just having herself a nice little after-dinner refreshing glass of Diet Coke.

But why was the white cat drawn to the Diet Coke in the glass in the first place?

Well, curiosity is always a strong instinct with kitties!

They may see you enjoying a glass and want to get in on the fun.

Some cats also prefer drinking from a glass instead of a bowl on the floor.

Also, if they have sensitive whiskers, which are their antennae for everything, they may not like it when they get wet from their water bowl.

Having their bowl in a corner of the room, so it’s out of the way, can actually make some kitties anxious because they feel isolated and can’t get a good view of their surroundings.

This is when those primal instincts come out, and they may feel vulnerable in this position.

But a glass of Diet Coke in the middle of all the action is perfect for them to keep an eye on everything and be on the lookout for predators (like maybe a goofy dog knocking over the glass with their tail).

Some cats also like to have their water and food separate, and that could include their Diet Coke!

However, even though this video of Feta enjoying a Diet Coke is very funny and relatable cat behavior, pet parents should be aware that Diet Coke isn’t the best drink for these fur babies.

Diet Coke contains caffeine, which cats are very sensitive to, and even small amounts can cause hyperactivity, rapid breathing, heart palpitations, tremors, vomiting, diarrhea, and lethargy, according to Petshun.com.

Caffeine toxicity can even lead to seizures, metabolic acidosis, or death.
