The game track of Catit is in my view a good investment for those who make it in time may not always be to sit down every day with their room and tigers to play with them - because hereby the chicks can let off steam. Tip: The lighted balls of Catit to be ordered separately, because in the game package track just a regular rubber ball is included, which should inspire most cats only moderately. The product can be converted and expand at will, so that you could build an endless game track theoretically, should have their bright joy with just pure indoor cats. Nevertheless, I would like to take this opportunity to emphasize that a toy - no matter how great it may be - can never be a substitute for the personal playing with her cats! Please take the time anyway, as often as possible to play even with their pets.
