Its true, these things are expensive and you do not know whether or not its worth all this money. Is this just a high strung kitty that will always be that way. So in essence is it better just to deal with their energy in play or such. My friend has tried it all, the money she has spent is ridiculous. Even was given the calm diet by science diet that was prescribed and she said she really didnt notice any difference. These cats are naturally high strung, with lots of energy. And it can get expensive. The calm diet food is almost 60$ a bag, and that can get costly. Of course we want to do the best but Im thinking a lot of this stuff can really add up. But what would they give the cat to help ease them nerves..? Im hoping to get my kitten soon but when I see what my friend is going through, I feel terrible for her, and she spends so much money.
