  • Yeah you really did not introduce them the right way. You should start over and do it properly, but first you should take him to the vet to get checked for contagious diseases that can be fatal to cats as you would not want to spread it to yours. They can also check for a microchip in case he is a lost pet.

    After that, you need to set aside a room that is not important or favoured by your cat Anya, and designate that as his room. You should also give Anya a space where he is not allowed to go at all so she feels she has a safe space from the intruder. Here is some instructions how to do this properly, it may take weeks or longer for them both to be comfortable:

    There are lots of similar instructions available. But you always start with them separate, then bring them something with the scent of the other one like a blanket (not pee or litterbox), then allow brief visual contact with a barrier, allow them to explore eachothers space when the other one is confined somewhere else, and then allow them to meet and interact while supervised, then allow them to interact unsupervised. Each stage can take anywhere from hours to weeks, but you cannot proceed to the next step until they are both completely comfortable. Cats are easily stressed at times and can stop eating or peeing and this can cause serious harm to their health or even be fatal.












  • Yeah from my brief reading it seems they can adapt to food salinity by altering their urine concentrations so I don’t think that’s a huge factor, at least it’s not something that comes into play before the other factors begin to harm them. But if you could fix their skin and buoyancy, diet may start to matter. But their prey is also a different salinity than the water it lives in a lot of the time, and sometimes they eat land animals like birds and such ofc.



  • There are types of freshwater river dolphins in the Yangtze (well, one of these species probably is extinct there as of recently but still) and the Amazon, for example. Sea dolphins can survive in freshwater for awhile but their skin isn’t adapted to it, and it will get damaged eventually. That and the difference in buoyancy in sea water vs freshwater leads to the sea dolphins eventually getting exhausted in freshwater.
