You could get a house on Poptropica. But not a pet. To get a house you could get a house on 24 Carrot Island! It's on the carrot farm. If you complete 24 Carrot Island... you have a mystery roomate! You go thru the chimney to get in. Is that easy enough.
The carrot farm is on 24 Carrot Island, but someone is taking all the carrots!

You have to find the lady in Charlie's Carrot Surplus store's cat, who is in the bathtub in the abandoned house at the carrot farm. To get the cat you have to get the bowl in the house and then ask the waitress in the Carrot Diner for milk and chase the cat down to the milk.
The farmhouse is past the Funny Bunny Carrot Farm, tothe left of Main Street. The house is closed up, but you can climb to the roof and enter through the chimney.
The carrot farm is to the left of Main Street. The only thing there is the abandoned farmhouse, where a missing cat was seen. The cat belongs to the clerk at Charlie's Carrot Surplus. (see related question)
This sounds like a particular glitch between the software and computer. There should be no reason you can't go left from Main Street onto the Funny Bunny Carrot farm.
On 24 Carrot Island, the milk is at the diner, and you can take some back to the farmhouse in the cat's bowl. On Shark Tooth Island, the coconut milk is given out free by the vendor near the start of the island.
Go left from Main Street and enter the farmhouse through the chimney.
