Because they tend to eat to much and if they had one they would explode with all the pressure from all the things they eat. In my opinion rats are dumb because if they would just chill out and stop eatting stupid things mabye they would be as lucky to have a gallbladder as us! I love my gallbladder i just couldn't imagine my life without it. Sleep well my darlings

Humans have a gallbladder, which rats do not possess. The gallbladder stores bile produced by the liver and helps in the digestion of fats. Rats do not have a gallbladder and instead secrete bile directly from the liver into the small intestine.
Rats do not have a gallbladder because their liver produces bile continuously, so they do not need a storage organ like the gallbladder to store bile.
Rats do not have a gallbladder because they have a different way of digesting food compared to humans. Their liver produces bile continuously, so they do not need a gallbladder to store and release bile as humans do.
Yes - only rats and horses do not have a gall bladder.
No. Rats don't have gallbladders either. Elephants do not have a gall bladder.
Rats, like some other rodents, lack a gallbladder because their diet is primarily herbivorous and consists of high-fiber plant materials. This diet allows for a continuous flow of bile directly from the liver into the intestines, which is more efficient for digesting such fibrous foods. The absence of a gallbladder means they do not need to store bile, as their feeding habits allow for constant digestion and nutrient absorption.
There are some animals that have evolved to not have a gallbladder - the horse is probably the most commonly encountered of these animals. The horse doesn't need a gallbladder - the function of the gallbladder is to store up bile between meals for digestion after the consumption of a meal. As horses have evolved to graze and eat almost constantly throughout the day, they don't have "meals" for the gallbladder to store up bile between and they evolved to not havea gallbladder.
The gallbladder. Horses and deer also do not have gallbladders.
Mammals, reptiles, amphibians, fish, and birds have a pancreas. Insects and arachnids have no pancreas.
There is no artificial gallbladder that can act as a replacement for the human gallbladder.

The gallbladder is attached to the bile duct by a small tube called the cystic duct
