My cat Timmy gets exactly one can of food a day...1 in the morning and he is very fat (not VERY fat) but he always wants more...and i only get out of school at 3pm and i don't normally come home after school. But he constantly whines throughout the day for food. What do you think? Should i change the schedule with times i feed him? Should i give him more food? He gets one can of Friskies a day...which is 5.5 ounces...is that too little or too much food for him?should i mix food with it? and if so...what? What do you feed your cats? I won't feed him 9 lives anymore and ever since i took him off of that he hasn't sprayed as much...but...what do you do?
