Wow, I am so sorry about this situation with your ratties. I know how it feels to love your little guys very much and to worry over them. I am hoping that some of the very experienced rat moms on this forum will be able to give you some sound advice. I have experience with rats but not as much as some of the long time veteran rat people on this forum, like Lilspaz, who I hope will see your post and respond.
Yes, it sounds like all three of your boys need definite medical care, what with the diarrhea, the sneezing and the red poryphin discharge. Mousey was correct about limiting veggies and fruits as this can contribute to the loose stools. Hopefully you can get your boys to a vet right away, or as soon as possible. I have not heard of vets giving Kaopectate type medicine to rats before? Or is that the norm? Anyone on the forum know about this? I am really sorry your boys are having a hard time.
Is your vet a small animal specialist? Does he/she regularly treat rodents and small animals, as compared to cats and dogs?
My vet has some experience with rats, but he normally treats average pets. I found him in my search for a vet who treats exotics, which rats are usually classified under for the rat who passed away last November. I may switch to Banfield as they told me they had a rat vet, I'm just worried they will be more expensive than this small clinic.
OK so I need a bit of a timeline and more information here.
1) How old is Bion? What did his cagemate die of? When did the foul diarrhea start? What is his regular diet?
2) Just sneezing with a bit of discharge for the babies? How is their activity levels, eating, drinking, pooping, playing? What do you have them bedded on?
1.) Bion had his first birthday in september, and his cagemate died in November. At the time we had recently introduced a hairless rat that we got from a man who said he breeds them for health and temperment. If anything, only Bion and Harley had bad blood for each otehrand fought now and again. (Once got my hand bit by harley while I skooped some stray poo into the litter pan and they started fghting on my hand.) I think Squee got in the middle, where he got his eye injury. Within three days he became lethargic and weak and I had to syringe feed him water and crush up their blocks for him to eat. He died 3 hours before his scheduled vet visit. Bion had always had a tiny bit of soft stinky stool occasionally, but since squee died and we seperated Harley into a different cage it intensified greatly. He normllay ate the Mazuri blocks with occasional treats. At the moment I mixed up a ratty trail mix to encourage him to eat more, his weight is nothing compared to the young ones.
2.) Only Bob has the severe sneezing, Squeak has small sneezes now and again andf I'm just observing him for now. Bob is starting to sound like a guinie pig which is what has me so frantic. It's been goin on for 3 weeks, and me and my fiancee are trying our best to save up and buy more time. Asides from that him and Squeak play and bounce around like healthy rat teenagers. They are dogging down the trail mix and Mazuri blocks and poop looks normal, if not numerous. I have them bedded on blue carefresh that I freeze the prior night just in case of mites and other hithchikers.
It sounds like the rats may have some sort of respiratory problem. But Bion can be mourning the loss of his friend. And newer rats can sneeze for a few days during the intial adjustment to new bedding. If their eyes and nose is runny then I would try to seperate them (room wise) from the other rat. A humidfier can help ease their respiratory problems as well until you can get them into a vet. Make sure if you can that it is a cool mist humidifier. If possible get one that doesn't require you to buy replacement filters as it can become very expensive. sometimes heated humidifiers can irritate their respiratory system. A domestic rat will usually live 1-2 years but some can make it to 3. Bion is a senior rattie. I hope this helps and I hope the ratties get better.
ps fruits can cause diarreah I'd ease up on that a little bit. if he needs encouragement to eat try some stale wheat bread crumbled with the regular food.
Its not the dried fruits, thats something I just started giving a week ago and nothing about his bowel movements has changed, and it is a combination of rolled oats, dried cranberries, dried strawberries, dried bananas,crumbled plain rice cakes, the red and green dried pasta, and crushed total cereal. I'm just trying to encourage weight gain in Bion cause he feels mich lighter than the babies who now match him in size.
