Warm the fluids before giving so it’s not such a shock to Susie’s system. Here’s what I wrote to Gina on Baba Kitty’s condo of a few days ago:
“Warm the fluids in a bowl or pan or sink of hot /warm water and leave them there for a while. Be sure to keep the line out of the water. Then turn it upside down (right side up, I guess) and hand/hold it up and let the cool water that will still be in the line to flow out and test the warmed water on the inside of your wrist/forearm like you would a baby bottle to make sure it doesn't feel too warm or hot to you. I know some people who buy a digital thermometer to scan at the bag to see the temp. I've never had to go to all that trouble (although it's a cool thermometer that tests the surface temperature of objects). This can help with some cats. Keeping in mind that the body temp of a cat can be from about 99 to 102 degrees you can either try to go a little above that or just to get it in that range. But, like I said, I don't actually measure the temp. I go by what feels comfortable on my wrist. Some people use a Sous Vide machine that circulates water around the bag at the exact temperature you specify (I don't have one of those either, but I guess I could cook with it

) So.... this is a lot of info and you'll probably come back and tell me that you already warm the fluids! If so.... my apologies!

You're an awesome cat mama!”
