My 10 year old moggy has started craving fat. She has always liked cheese, eating the odd bit of grated cheese dropped by the DCs but she is now licking butter and mayonnaise off any plate or surface. She meows like bonkers if she can smell a 'fat'. I have never given her milk or any dairy product, just the bits she can hoover. Has anyone experienced anything similar? I wonder if she is craving fat could she have dry skin and could I maybe give her cod liver oil? And she is definitely not a lap cat so examining her skin is not that easy. Any advice would be really welcome.
