# Lipid Fraction Properties of Homemade Raw Cat Foods and Selected Commercial Cat Foods
## 5 Conclusions  
* The self-prepared cat foods contain high levels of EFA, which is beneficial for adult cats and essential for the cats' growth and reproduction stage.
* For the first time the distribution of FA in TAG for cat food has been determined.
* The commercial and self-prepared cat foods have a similar ratio of omega-6 to omega-3 but self-prepared diets provide more EPA and DHA.
* It is shown that the type of meat in self-prepared cat food affects the composition and distribution of fatty acids.
* Fat samples from self-prepared cat foods containing beef are characterized by the highest oxidative stability, which can be due to a lower ratio of PUFA/SFA.
