rat behaviour

Does or Bucks (girls or boys)?

When it comes to deciding whether to get bucks or does there is much to consider. Among rat enthusiasts, the debate on which gender is “better” makes for lively debate. Both bucks and does make great pets. I have to admit to loving both does and bucks equally, though it is a lot easier to keep only one gender because you can get all your rats out at one time daily rather than having two different play times, one for the boys and one for the girls. So, if you want to make your life easier, stick to does or to bucks. If you want both genders, however, I totally understand. In fact, there are some nice cages that will allow you to keep both sexes easily enough as the cage divides into half with an opaque tray between the two.

There are a lot of generalisations about the differences between bucks and does and we may as well start with them. So, true or false?

True of False? Bucks Are Lazy; Does Are Lively

There is some truth in this! A female rat, or doe, is often smaller, sleeker, and more active than her brother. While everything comes down to individual personality, does tend to be far “busier” inside their cages, racing up ladders, crossing ropes, building elaborate nests, etc. By contrast, boys tend to do as little as possible to create a nest, then flop down and sleep the day away. But at night, things are different! Boys will want to come out and play just as much as the girls will! they may not play as fast or for as long, but my boys race over me as I watch a movie, sit on my books and explore my eyeglasses while I’m trying to read, jump from one shelf to another just for fun. Girls are faster (no contest there) and tend not to sit on your lap as much as boys, but all this changes with age.

By 18 months, many of my girls will slow down enough to sit on my lap. The boys at 18 months will probably cuddle longer and be less likely to “race” anywhere!

My girls will frequently climb up my leg to get to me. My boys might come over to my foot, think about climbing, then change their minds.

If you have children who want to play with the rats during the day, girls are probably a better option, though the boys may learn that playtime is during the day and may wake up especially just to have fun.

True of False? Bucks Smell More 

In my experience, this is true. They’re bigger; they eat more; they have more oil in their coats. I don’t mind this about bucks but if you are someone who really hates the smell of rats I’d go for smallish does. Does tend to weigh between 350–500 grams, but can be more! Male rats range from between 450–700 grams. I have heard of a couple that top 850 grams.

Another point: if you are mildly allergic to rats you may get on okay with does but not with bucks.

Caution: bucks mark more, which means they dribble urine sometimes. If this drives you crazy, go for does.

True of False? Bucks Cannot He Introduced to Other Bucks

Not exactly true, no.  An adult buck will usually accept a couple of baby boys, ages 9-14 weeks, without difficulty as long as the introductions are done correctly. But introducing adult bucks to adult bucks is trickier. I’ve known people who have done it without any problems but please remember that rats who are strangers to one another can fight. The injuries can be serious or even fatal.

Those who are successful at introducing adult bucks to adult bucks almost always use the “carrier method”, about which I will write shortly. However, I personally do not like to introduce adult bucks to one another. I’m too concerned about injury.

By contrast, I have successfully introduced adult does to adult does with little to no fuss. I use the carrier method and watch for any signs of trouble. All my intros have been incredibly easy. This may be due to the rats I have, but I think it is true to say that does are generally easier to introduce to one another.

Everything depends upon individual personalities, of course.

True of False? Does Are Indifferent To Their Owners

Completely false! Makes me mad when I hear this! Does adore their owners! They just won’t sit in your lap for very long until they are a bit older. Have a look at Missy in this video and you’ll see that does can be just as much of “lap rats” as boys. However, everything depends on the age of the rats, how much you handle them, how much time they have to explore, and the “line” from which you buy your rats. Some lines produce more active rats than others. I am breeding for calm docile rats that make great pets. I don’t mind if they never win in the variety classes at shows — it doesn’t bother me at all.

I might add that bucks are pretty darn active as youngsters and that while some are licky, lovey “squishes”,  some don’t want to be “lap rats”. Again, it all comes down to the individual.

True of False? Bucks Are More Likely to Be Aggressive

Apparently, this is true though in my own experience, my bucks aren’t territorial or at all aggressive. They don’t bite me and I’m always reaching into their cages and messing about with “their” stuff. Both bucks and does tend to taste your toes — I have no idea why — but they don’t bite them as such. They may decide to give your fingernails a manicure, too. This amuses some, annoys other. Does will sometimes get a bit shark-like just after giving birth (though often not). Bucks begin “play fighting” at about 5 weeks of age and will occasionally get into scraps with each other as adults. Does do the same, but at a lower level.

Do not try to break up a rat fight with your hands as you could get bitten in the process. The problem with rat bits is that they HURT. And bucks are bigger so,if you were to get bitten, it may be more serious.

True of False? Does Live Longer

Statistically, this is true In general, does live a couple months longer than bucks. This may be because bucks tends to gain more weight than does in their later lives. There’s a wonderful website with all sorts of statistics on rats. Among the various graphs and charts is one that shows how rats pretty much continue to gain weight throughout their lives, with the boys being more likely to become obese unless their diets are carefully controlled.

True of False? Does Have Bigger Vet Bills

Probably true, unless you have to neuter your male rat in which case, they will likely cost as much as a doe.  A does may need a spay or to have mamary tumours removed. Some rats never seem to get mammary tumours. Others get enormous ones. Bucks can get them, too, but are less likely to do so. I’ve had two does spayed recently and both bounced back really nicely and are now genderless, happy middle-aged rats who I hope live good long lives!
