sorry for your loss =(...i know how hard it is.. its like loosing a part of you... I actually went through the same thing we had a cat that grew up with my 1 1/2 yr old yorkie and one day she was gone... he got exactly like that.. he wouldnt eat he didnt want to play.. I was more worried about the eating part.. what I did i went to Vons well any supermarket will do.. and bought him meat gerbers and he actually ate =) yey.. but it took him almost 2 weeks to be himself again.... even now there still times that i think he still misses our cat lexy.. since he will go to her old bed and just play with it... after a yr.. i finally got him a new playmate which is another girl this time is a yorkie.. =) i wish I would of done it sooner.. cuz that brought him and all of us.. a lil bit more happiness. eventhough our kitty lexy will always be in our hearts.. and we still miss her
I hope this helps..and good luck =)
