I will travel to South America in the beginning of November. My cats are very affectionate. It won't be good for them to be alone such a long time. My mum will have a look for my cats as well. So it won't be necessary to stay all the time. Moreover you have also the possibility to visit the sea or Berlin and my mum would come than.
I have 3 cats. It is not sure if I have a foster cat (Luna) than as well. My cats are very uncomplicated no pee or puh on places where it isn't "allowed"! Yuki ist very independently - not interested in cuddling with strangers. Piratat and Sam love to sleep in the bed and they cuddle with everybody. Sam is a bit rough sometimes...
of course you should clean the apartment at that time as well. Smoking is not allowed. But there is the possibility to smoke in the garden.
I have Tv, blue ray and wifi !
