Yes, let them slowly adjusted to one change and make sure they are happy and stable before proceeding to the next change. Cats have psychological needs similar to us and changing too many different things can mess with them. I saw a new side of my kittens when introducing raw, trust me raw (if not fed in isolation) will be a bigger change than switching wet/dry foods especially in a multi-cat household.@Zoop I do have a spare room so I wouldn't mind introducing raw food to them one at a time. It's an enclosed space and it would be easier to clean up in there versus another area since there are plenty of places to run away with the food to.
I'm thinking introducing new wet foods to Sareena might be a little difficult after a couple of months of exclusively different flavors of Friskies but her previous owner didn't always have the financial means to feed her so they fed her a variety of things including rice and boiled chicken. Here with me she's only ever ate cat food both dry and wet. I will say she gave me a hard time with 9 lives wet food and dry food. She wouldn't even go near it.
I'm almost positive Elsa is the dominating personality here. But Harley will def give her a run for her money. Quinn is really laid back and Sareena keeps to herself mostly. It would be interesting though to see how well they would take to raw feeding. Do you recommend that I wait till I have the timed feeding down pat before I introduce any of them to raw ?
