We have out new kitten Inka now , who is longhaired too .
As far as now , there was not any problem ; I comb her hair 2 times a day , and she seems to "undergo" it ( is not the same as "like it" ...) . What she hates is when I try to comb her near her "behind" !!! gee , lots of hissing then !!!
During her first week after her rescue , I had to cut a way some long hair around the anus because of the runny diarhhea ; was easier for her , AND for us to clean up the mess ...
