Poopy was kept in a separate bedroom. Mind you she was hospitalized for several days while her radiation level was too high for her to be in the home safely. While she was "quarantined" I did pet her and love on her and spend a lot of time with her. She did not sleep with me/us (had a now ex-partner at the time who was allergic) so that was not an issue in my case.
I had to wear rubber gloves to handle her litter for two weeks. As I recall, that was the extent of it. She was able to have the run of the house again after about the same amount of time.
I am confused. Is M saying that he will not agree to her receiving the treatment, or that he intends to ignore the vet's instructions to keep her isolated until she is no longer radioactive?
In any case, I think he's in the wrong here. There is a risk of exposure to radiation for a week or more after this treatment, and following the guidelines will not damage either the cat or frankly M. She will feel so much better after this is over. Poopy sure did. There were so many things that I did not attribute to this condition that turned out to be related, for example excessive grooming. Her tummy was pink because she groomed all her fur off! After the procedure her fur grew in. And it was beautiful. She was much calmer and seemed happier all the way around.
Please insist that the cat receive this treatment. And if M wants to take the risk of exposure to radiation I guess that is his choice, but in our case neither cat nor people were worse for wear after following the directions.
