20 Baby Pets That Turned Into Big Boys and Girls Before We Could Even Blink

We sometimes tend to think that animals are born more prepared for life than human babies. For many species, this is true, but not for all. For example, when kittens are born, they are both blind and deaf. With that said, they develop pretty fast and start to see and hear after just a week or 2.

We at Now I’ve Seen Everything have found 20 photos showing just how rapidly our little friends change.

“What a difference a year makes...”

8 weeks vs 6 months

“An 8-week-old puppy to a 9-month-old derp”

A majestic glow-up

“From day 1 to 8 weeks to 1 year old”

“Hjalmar on the day I got him, and exactly one year later!”

“Bean was a microkitten. Here she is at 8 weeks vs 5 years.”

“It’s my beast’s third birthday tomorrow!”

“2 months to 12 months — we love our big floofy Samoyed boy.”

“Puppy snoot -> doggo snoot”

“From 2.5 months to nearly 2 years”

“Marvin, 1 month to 1 year”

“Still a puppy (7 months old) but the growth is insane!”

“Thor, then and now”

“My old girl turned 14 today.”

“6 weeks to 8 months!! They’re getting too big to hold.”

“From 3 months to 3 years”

“Casper at 3 and 13 weeks old”

When you’re huge but still a baby inside:

“1.5 months to 10 months, boyfriend for scale”
