How do I get more pet bowls so I can have more than 2 pets?

If you had played virtual family 2 . Their was a option for buying pet food bowl as many as you want. But buying more than 1 bowl never helped me. I had 3 small black kittens. 1 snow white cat. One brown cat and one dog . When I click at 1 bowl all cats and dog start eating from that particular bowl and when I click 2nd bowl to add food they all go and start eating food from their so basically I wasted money on 2nd bowl . 1 bowl is enough for all the animals.
Now in Virtual family 3 their is already a food and water bowl placed in kitchen.if you had animal food the bowls will always have food in them and if I have to buy food for animals I can check how much food is left on clicking on those animals food bowl to check food quantity, basically we can't buy more bowls but we frequently have to buy food for animals so the food bowl never goes empty.
