Siobhan,
We all go to buy certain things at the pet stores and wind up with a bunch of other things. I think its part of being a cat lover. While you are at it, invest in one of those small laser pet lights for your kitties to chase. Its quite fun to watch them try to climb up the walls to catch the light. Of course, when they get older, they get a lot smarter and they figure out where the light is coming from, but sometimes still chase it anyway. We have had a lot of fun with that light and its a good way to make sure the cats get exercise.
We have Royal Canin food in the US and have for quite awhile. Its a decent food and rates pretty high. Be sure to look at the ingredients to make sure there isn't any corn at all or heavy grain products listed in the first few ingredients and no by-products instead of real meat. The meat should be listed first in a good food. The more grain in a food, the more digestion problems you may be dealing with. :unsure:
The time is close for you to get your kittens, huh? I haven't heard anymore from you about the one kitten that was being evaluated. How did that come out?
You are right in being so careful.
Nan
