I actually own one of the pink guinea pigs you guys are talking about. I didn't realize this epidemic has been going on for awhile, nonetheless, I'll share my pink guinea pig story.
I work at a local pet store (which I will not name, hopefully that will be respected), and every week we receive a shipment of baby guinea pigs, about seven or eight at a time every week because they sell so fast. Typically the guinea pigs come to us as little babies, only a couple months old. And I'm sure you know the drill, we gotta hold them and cuddle them, give them kisses and love them because it's just so darn hard not to!
Anyway, I'm one of the main openers for my store so it's my job to feed all the animals, give them fresh food and water, give the small animals fresh food and new water (if they need it), give them all treats I brought from home, and so on and so forth. Now, in the very back of my store, we have a somewhat small room where we keep "new arrivals" i.e. the guinea pigs, hamsters, birds and such. I also go back there to check the animals, give them food and water; I check the hamsters, make sure none of them have wet tail and if they do, they go in a deep cleaned habitat and separated from the rest until well again. Once that part of my routine is clear, I move onto the guinea pigs -- my favorite part.
Now the guinea pigs are kept in very large, separate bins, with two water bottles, a big hut and a large feeding dish with timothy hay in the corner. This is where I encounter my current pink guinea pig, Wilbur. Wilbur was among a few fancy guinea pigs, some with long, crazy hair all different colored who were a bit erratic, super nervous and scared because they were in a new place. I thought they were adorable until Wilbur finally caught my eye. He was crouched in the corner, frightened and nibbling hay nervously and unable to contain myself, I quickly scooped him up to hold him in my arms and then I noticed he was pink! I thought perhaps it was his skin, so I pulled his fur back a bit to check only to realize his fur was pink. I spoke softly to him, telling him what a little cutie he was, especially since he's pink, and immediately Wilbur started cuddling me. He would nestle under my chin and make soft wheeking noises while I would pet him, and give him kisses.
I think this is when I first fell in love with him, and realized I couldn't live without him. Once done there, I moved onto the isolation ward where we keep are sick animals, medicated them, observed any "injured birds" we had (someone thought a parakeet had a swollen foot because it got caught. Turns out this particular parakeet is just super clumsy, and isn't as graceful as her kin). I spoke to my manager about Wilbur, asked why he was pink and all that. She said she couldn't tell me why he was pink, but corporate was going to look into it. Apparently before I started working there, there was another pink guinea pig and he was super healthy, seemed to be sturdy, acted like a normal cavy, until one day they found he had passed.
My manager didn't want to put Wilbur on the floor because of this, and worried about selling a sick or injured guinea pig to a customer, only for them to come back a week later complaining of a death. Well, to say the least Wilbur was kept in the back for three weeks with his guinea pig friends until it came to the day his friends had to be put on the floor...
I wheeled the bin out of the back, Wilbur and friends in tow, unlocked the cage and put the three long haired babies in their new temporary home-- except Wilbur. I held Wilbur in my arms, let him cuddle me as I had usually done. At this point, it had become routine for me to tend to Wilbur first, as I had loved him and desperately wanted to take him home. Once his friends were secure in their new home, I took Wilbur into the back once more where he sat in his bin, alone.
For the next week, Wilbur was...well, depressed. He was by himself in an unfamiliar place, his only companions in the world were sold immediately and he was by himself. This made me feel guilt and pity for poor Wilbur. I spoke with two of my managers, told them I'm taking Wilbur at the end of the day and I would be back for him after my shift. They were fine with this, as they had already known how much I adored Wilbur, and so I came back. I bought a brand new cage, pink litter to match his pink fur, fancy new chew sticks, ox bow food, Timothy hay and treats. Oh, and a small little bed he sleeps in every night, along with a harness and leash.
It's been a week so far and I'm happy to say, Wilbur is the happiest he's probably ever been. Everyday he gets his favorite treat--romaine lettuce, cuddles, all the hay he can eat, a small amount of apples and whatever else his little cavy heart desires. He's very healthy, happy and piratically popcorn's all day, especially during playtime.
But I have noticed, in the week that I have had him his pink is starting to fade a bit. I theorize that now he's happy and healthy, is getting treats that are rich in vitamin C and has constant stimuli, that maybe the pink was brought on by perhaps a dye or vitamin deficiency? If that makes sense? I can try to post a picture of him on the forum so you all can see him in his adorableness, and see how truly pink he is and make your own thoughts on the subject.
