Post pics of your catters/puppers when they were babies and what they look like now.
I'll start, this is Polly as a kitten...
...and this is her now (4 years old).
Chloe when she was 4 months old
Chloe now (1 year old)
she hasn't really grown all that much desu mostly just got fatter and mellower
About 2 1/2 years old now
And now, at 2 1/2 years; bigger, angrier, and even lazier.
Unknown age, rescued after I saw him thrown from a person car in front of my house.
This is him 10 seconds ago at 5-5.5 years of age.
