I have only 1 kitten; Kovu.
Found him abandoned when he was barely 2 weeks old. He's almost 5 months old now. Have a few hamsters as well (i'm not trying to bring Tom & Jerry to life), but the hamsters have been here longer. & ... a guinea pig.
He's basically eating Royal Canin, I bought 1st choice once but thought the kibbles are a bit too large for kittens. hmm ...
How many feline friends do you have? And how old are they now? Were they well behaved when younger? I have plenty of scars courtesy of Kovu. Yikes.
I've purchased from petshack quite a few times. They're ok in my opinion, but have limited cat stuffs. They used to have free shipping for orders over certain amount, but no thanks to d shipping charges hike as you've mentioned, no such benefit now.
Nice talking to ya.
