How long do hamsters really live?

Our pets can’t stay with us forever, but the right setup and care will prolong their time for a good while. In fact, life expectancies of many indoor animals have been steadily increasing as we perfect their nutrition and homes. Still, we only can have our sweet companions for a handful of years (unless you decide to bring home a tortoise, in which case prepare your great-grandchildren to inherit it). While in dogs a smaller breed typically lives longer than a larger one, for small pets the opposite is true. Bunnies have a better life expectancy than guinea pigs, who make it more years than hamsters. While no one wants to say goodbye to a furry friend, realistically looking at a hamster’s lifespan can help you plan ahead.

What is the lifespan of a hamster as a pet?

This varies a bit based on what type of hamster you bring home, but you should expect to have him in your care for two to three years. Of course, if you adopt an older hamster, that will shorten the amount of time you have together, but does provide a noble and necessary service for abandoned pets. The oldest hamsters live to reach four, and if you’re lucky, you’ll have one for that long. If longevity matters to you, in particular, seek out a Robo Dwarf Hamster, which has the best shot of getting to a ripe old age.

What ailments afflict hamsters?

We certainly hope that old age eventually comes for your pet after he’s lived a long and happy life. But hamsters, like all animals, do tend to get certain illnesses. One of the most common in these little guys is a cold. You’ll notice by spotting the telltale signs: runny nose, droopy eyes, and sneezing. Your vet may give him something to manage the symptoms a bit, but mostly you simply have to wait it out (just as you would if you were sick). However, don’t confuse a cold with wet tail, a deadly disease that can kill in 24 hours if untreated. If your hamster’s underside is moist, call the vet immediately and get him on antibiotics (and possibly fluids).

How can I help my hamster live longer?

It all comes down to a good diet, lots of exercise, and a peaceful environment. Many hamster sicknesses are brought on by tension, so you want to do your best to avoid stressors. That means eliminating things from the area that would bring on anxiety, such as other pets. It’s completely possible for a small pet and large one to coexist, but they need their own spaces far away from each other.

In terms of food, make sure you provide hay, fruits, and veggies, plus commercial pellets to round out your hamster’s diet. Most importantly, he needs continuous access to water as hamsters like to drink. Lastly, especially because most hamsters live alone, you need to keep him entertained through tons of toys and plenty of attention.

Give them love

With a loving hand, you can keep your hamster happy and healthy for many years. Remember that the Syrian variety prefers to be alone and cannot be kept with others of its kind. Therefore, you should plan carefully and wait for one to pass on to the happy nesting grounds before you decide on another. Keep in mind too that while affectionately known as a starter pet, these rodents need attention and lots of care. Make sure you’re ready for the commitment before bringing one home, even if it’s only a three-year promise.

Do fish sleep? It’s complicated
You'll probably find your fish resting periodically — don't panic
Fish resting in an aquarium

You might see your little swimmers still and peaceful in your tank and think that they're sleeping. But do fish sleep? It's complicated because first we have to define what sleep even means. Research says that many animals do rest and that slowing down intermittently helps with all sorts of processes, including things like fighting disease and recharging energy. So while fish don't sleep in the same way humans and most other mammals do, they still rest periodically to help them stay sharp.
How do fish sleep?
First, let's talk about our sleep. You'll notice that when we go down for the night, we almost always close our eyes and our furry friends do as well. That's thanks to our neocortex, which shuts off so we can get some shut-eye every night. Dogs and cats operate much the same, though they sleep at different times than we do (practically all day, in the case of cats).

Fish have neither a neocortex nor eyelids, meaning they can't sleep exactly the same way as humans. Researchers at Stanford studied fish brains and found that they do seem to be sleeping, though aquatic animals likely don't enter REM state (dolphins, too, have slightly different sleep methods). Sharks take this even further by swimming even during sleep — if they stop, they won't be able to keep breathing!
When do fish sleep?
You may be surprised to discover that fish usually sleep at night and spend the day awake. That's great for us to get prime-time aquarium viewing. Still, some fish are up at night, especially a few species of catfish that will do the bulk of their feeding in the wee hours of the morning. Interestingly, a few fish don't sleep at all, including some species of cavefish that live entirely in darkness, and many baby fish, which don't develop this ability until adulthood.
How do I know if my fish are sleeping?
As with all animals, you probably want to leave your tiny sea creatures alone while they get some rest. You don't want to get woken up from a nap, either, after all. Check for signs that they're catching a few z's. Fish are possibly sleeping when they stay motionless for a while, lay down on something in the tank, and don't respond to things going around them. So if you walk up to your fish house and see one snuggled up in the corner, they're probably fine. Come back later to make sure they've moved rather than tapping on their home to rouse them.

What fish can live with bettas? These are your best bets for fish buddies
Bettas can't live with one another so you should look to other species for friendship

Betta fish are known for being territorial, feisty, rather combative, and therefore not great tank mates in general. This reputation, however, only holds true in particular situations and with certain fish friends. Male betta fish are aggressive, but only with other male bettas, so it is important to never put two males in the same tank. It will lead to tail-nipping behavior and other aggressive actions. So, what fish can live with bettas?

Happily, there are several other fish that can keep your betta company in a safe and non-aggressive environment. Many colorful, friendly fish cohabitate well with bettas. This is our guide to finding the perfect fish companion (or companions) for your betta.

Rabbits are pleasant house pets — a delight to care for when you know how to keep them happy and healthy. Like other beloved animals, a pet rabbit’s life expectancy depends on their breed, diet, and living conditions. What is a pet rabbit's lifespan? Let’s dig a little deeper and answer some important questions, such as how long your adorable pet rabbit lives and how to extend their years.

How long do rabbits live?
Here’s a fun fact: The oldest rabbit that ever lived was 18 years old! By contrast, wild rabbits only live up to about three years, since many die very young. But there's good news. In the absence of predators, pet rabbits have a life expectancy of eight to 12 years. Like dogs, larger breeds tend to have a shorter lifespan while smaller rabbits often live at least 10 years.
