Hi Keith-
I'm glad you'll be doing the sub-q fluids (hydration) - it's the single most important thing for a CRF kitty. The sooner you start, the better.
Once a week is a cinch - some folks do it every day.
A couple of tips:
1) Make sure to warm the fluids before you administer them. You can put the fluid bag right into a sink full of warm water. Many vets won't take the time to do this, but you should when giving fluid at home. To warm a full bag (1000mL), about 5 -10 minutes should be fine; it will take less time as you use up the bag. Always test the fluid before you give it by letting some run out of the needle onto your wrist.
2) Use a 20 gauge needle. Vets use an 18 gauge because it's a larger needle and the fluid comes out a bit more quickly, but a 20 gauge is finer and will be more comfortable for Jasmine. Always use a new needle each time you hydrate her.
The websites other members gave you are good ones. I referred to them plenty of times when I first started.
Jasmine's numbers aren't too bad right now. With regular hydration, they should go back into the normal range. BUN can change often, depending on what the cat has eaten. Creatinine is considered the more "important" number to watch. At the lab my vets use, a creatinine of 2.4 is high normal.
As other members have pointed out, diet is important, and wet is better than dry food. I'm not crazy about Hill's products - IMO it's inferior food at a premium price. Most vets recommend that food because they sell it. You want the highest quality food that you can buy. For my cat, Wellness (grain free) canned food worked best. She got California Natural dry food only as a treat, not for meals. We also gave her fresh roasted white meat chicken and turkey. Keeping weight on cats with kidney disease can be challenging. Don't force Jasmine to eat food she doesn't like.
Very important: please keep a very careful eye on Jasmine's blood pressure. High bp often accompanies kidney disease and can be deadly. Make sure you get regular blood pressure readings at the vet. If she does develop high bp, there are meds to control it.
Since Jasmine is hyperthyroid and the meds are causing appetite problems, you might want to look into I-131 treatment. It's expensive but in most cases it cures hyperthyroidism, eliminating the need for meds.
I did sub-q fluids for my Mickey for over 6 years. We started as soon as she was diagnosed. For the last 2 years of fluids we hydrated her 4 times per week. In addition to CRF, Mick had liver disease and IBS. I lost my beautiful Mickey this past December. She was 21. I have no doubt that hydration extended her life.
I hope you and Jasmine will have many more happy years together.
