Depends on how old is Milo. If he is less than 1 month and he can grow really big but if older than 4 months old then not as much. But there will be improvement from just feeding him Prestige and fresh veges.

He has passed the growth spurt period from 2 weeks old to 4 months old.

Try the smoothie for a few weeks and see the growth.

Just want to share something...

I went to Pet Safari at Ikano 2 months ago. U know that corner that sell hamsters in Pet Safari? That Corner does not owned by Pet Safari..
Anyway, when i was there, i was to buy beddings and check out the cute hamsters. Then i saw ONE particular hammie isn't moving. So i stood there and observe.
After few minutes, I realized that hammie is actually dead. And no one knows cos too many hamsters in a tank.

So i walked to the shopkeeper (assuming is the son in his college age), i told him one of the hamsters is dead. So he took newspaper and picked it up.
I continue looking at them. Cos they're not given enough food. After a few seconds, i found something. I hesitated and doubt. Could it be? Could it be not? I saw something flat like a hard paper. I look closer.

OMG!! OMG!!!    Another dead hamster! But this one, died longer cos it's FLAT already. I ran to that guy and told him another dead one. Flat and left back the kulit. U know what? The idiot and his mother laughed, "More dead hamsters? What? Left back skin? Hahaha..." I got so angry     . How can you laughed like that. I feel like slapping him.

So he picked it up. Meanwhile, i check other tanks to see if there are more dead hamsters. True enough, we found another TWO. So in total, there are FOUR dead hamsters in the tanks and no one notice. How cruel!!! I love hamsters and i had many hamsters before. Looking at how they treat the hamsters, i feel like buying all of them and bring them home.    

Then, we walked into the corner. Mom was checking out the iguanas. Then she told me she saw one interesting iguana that look like got lipstick on. Red lips. I was curious and looked at it. OMG!!! OMG!!!    All iguanas in the shop are injured. They are not wearing lipsticks. Their lips were injured. No more lips. Can see teeth. And bleeding. Can see blood on the tank's wall. I felt so disappointed and disgusted by the shop owner and i walk off.
