Sounds great!
But, did the vet also give you a probiotic? Something to replace the flora in his system? An antibiotic kills
all germs, the good ones and the bad ones. Flora, one of the the good ones, must survive in order to keep the chin's digestive system flowing properly. When using an antibiotic and a probiotic during the same period of time, they must be given at least 4 hours apart, or they will just cancel each other out, and it will be as if you are using neither. A good probiotic is acidophiles. This can be found in most health food stores. Usually it is in a capsule form. To replace the flora ... 4 hours after the antibiotic medication, open one of the acidophiles capsules and sprinkle about 1/4th of it on a small amount of food in a special bowl.
Remember ... once the acidophiles bottle is opened, the whole bottle of acidophiles needs to be kept refrigerated or it will go bad.I'm not trying to scare you by what I say, but just wanting make sure you have a good holiday with your little one ...
But, if the flora/good bacteria dies and is not replaced, a chinchilla can become impacted/stopped-up in a matter of just a few days (2 to 5), because his food is not being digested properly. When this happens, his system shuts down and he can die from this.
Two of the first signs of this is that he will cut way back or even stop eating and his poops will become fewer in number and smaller.
Please keep a close eye on his feces/poos. If they become wet and sticky then/or smaller and dryer, he could be in big trouble. A chinchilla's poop should always be moist, but not wet ... soft, but not sticky ... oval and a healthy size, not smaller and dryer.
Once a chinchilla shows sign of being sick, he can go down/get sick/die quickly, much more so than a Guinea pig, which is one of the worst for this, but 'chinchillas have the Guinea pig beat hands down', to quote my vet. When a chinchilla needs help, he needs it right then, not later on. A chinchilla will hide an illness until it is almost to late to do anything. {This is the only way they survived in the wild... a sign of illness or weakness made them easy prey.}
The after hours and weekend cost of a vet are usually high, so it never hurts to be prepared ahead of time. I like to avoid the problems to begin with, if I can.
