When we see our cats running around the house, leaping, jumping, and generally causing all sorts of mayhem, it can be hard to remember when they were just tiny kittens that could barely stumble in any direction.

Japanese Twitter user @Neko2Obasan has cat lovers with hearts in their eyes, as they've shared an adorable reminder of how small their cat Tsukushi used to be. Tsukushi, now a grown and happy-go-lucky feline, can race up and down the ladder stairs to @Neko2Obasa's loft, wasn't always so agile and graceful.

To the delight of many feline fans online, @Neko2Obasa posted a photo of when Tsukushi was but a tiny kitten, and wasn't quite capable of getting down a step after climbing onto one. The look he flashes his owner is just too cute for words.

"When Tsukushi was younger and couldn't climb down one more step."

The combination of Tsukushi's dangling leg after he couldn't quite get it down onto the next step and his bashful look of knowing he needs help getting down has quickly spread on Twitter, with cat lovers saying they know and remember that kind of look all too well.

Of course, @Neko2Obasan's own heart was melted by Tsukushi's look at the time and quickly helped him down. Now that Tsukushi's all grown up, the stairs are no problem. Although he does seem to flash a similar look sometimes!
