Recently, we rescued three kittens from the same litter as the mother cat was abandoning them. One of our kittens that we rescued sadly passed away and another one is now showing most of the same symptoms. Mentioned symptoms are for example fatigue, general sleepiness, etc.
I want to know the chances of the kitten from the same litter being sick as well or if she is just sad because a loved kitten passed away (the kitten did see the other one pass.)
I'm not sure if cats do mourn others, though. We are going to get claramox just in case, as we don't have money for the vet.
I am asking for professional advice anywhere I can before moving forward, because then again I have no money for the vet.
The cat's precise age is unknown, but weighs about 1 lb (0.45 kg) or very close to that. It is mixed breed and female.
Please respond soon, thank you.
