Here is one that has me stumped...

I know someone who has adopted a feral kitten, she has had her spayed, shots, etc. She tells me that the kitten stinks!
She says it smells like kitty poop. The first thing she did, was to check for dingleberries...there are none, so that isn't the problem....(that would make it too easy)
Her other cat spends time cleaning this kittys butt, I guess he thinks it smells too....what could be causing this? I think the kitten is around 6 months...
