I'd have to say "do what you're most comfortable with" when it comes to pets stores. I've gotten most of my present rats from pet stores (except for 2 which I bred myself), and of my other 12 which I had, 2 of them were pet store rats (including a BLUE one!) and 10 of them were from a litter I raised. I know for a fact that of the 8 pet store rats I've had, 6 of them were from harem breeding. The other 2 were bred right at the pet store and are both types of rats that I wanted (dumbo rex and sphynx/hairless).
The OP's question was not "How do you stand morally in regards to buying animals at pet shops", but was actually a question on the hairless variety itself, and I can see many who went way off topic spouting their moral view. People don't post specific questions in order to be preached to. I can understand how many are very adamant and are staunchly opposed to pet shops, and I can really level with them. But it seems the OP already has her mind set on buying from the pet shop, and considering it's her decision to make, I have no problem with it. And how do you (general you) know that the pet shop doesn't breed responsibly? The pet shop I bought my hairless at was very informed and bred a sphynx with a hairless carrier doe because they knew that hairless does don't make good breeders! They only got 4 hairless babies out of the bunch, and my Jadon was one of them. He's been handled a ton since the day he was born and is the friendliest, most loving pet shop rat I have ever been owned by! This definitely is not the standard for pet shops, but that's been my experience.
On to the original topic, hairless rats are wonderful pets. They are a tad more difficult to care for because of temperature and sensitivities, but it's worth it (in my opinion)!
Hairless are wonderful, just research just like you would with any other animal before you get one. Every animal has different needs!!!
How right you are! I did a ton of research and learned so much just on a few sites! Odd Fellows Rattery is one with a lot of info! Do a Google search...you'd be surprised how popular Sphynx's are!
Here's what I found out when I did my research:
~They need their cages cleaned about twice as often as furred rats because the ammonia/urine smell is hard on their delicate lungs, especially if they are kept in a tank. They also should not have wood shavings (unless its Aspen) because it has allergic properties for hairless (their eyes leak usually if something is making them sick). They should have a low dust litter (recycled paper pellets are great, or corn cob).
~They need extra protein to build up a layer of fat for warmth, this can be supplied with a high quality dog or cat food (I use Iams because I have dogs and cats), or by adding chicken, beef, or fish to their diet. They also eat more than furred rats because they have a high metabolism which serves to keep their temperature regulated.
~They should be kept at a minimum 70degrees for a single hairless, or 60 degrees for more than one. You can have more than one hairless together to distribute warmth, but I prefer to keep Jadon separate from other rats because he lacks the protection of fur and will get scratches easier. I keep a ZooMed heating pad under the spot he designated as his nest and provide peices of old cotton socks as well as polar fleece. If they do get scratched, you can put some peroxide on the scratches and then rub in a bit of neosporin (but make sure it's rubbed all the way in).
~They are different in personality, I've found. My furred boys are rambunctious, but Jadon just loves to be cuddled and rubbed behind the ears. He could sit with me for hours just chillin' out. My furred girls are rambunctious as well, but I've heard hairless does are even more so.
~As was mentioned, if you get a hairless doe with the intention of breeding, you've wasted your time. Hairless does (females) should not be bred. They tend to have problems with lactating, and most breeders have found that they eat their young and just generally don't care about them. The best way to get hairless babies is to breed a hairless buck with a furred hairless carrier. About %50 of the litter will probably be hairless. I plan on breeding Jadon with my dumbo rex Avery because they both have such beautiful personalities!
Even though it seems like they are a lot more work, they really aren't much more work than my other 7 furred rats. They are very enjoyable and I really don't mind the extra care...it actually makes me feel closer to Jadon because he requires more care than the others...kind of like the nurse falling in love with her patient. LOL
I hope you are confident in whatever decision you make!
