Good morning, Emma.
I am very glad to hear that nothing sinister has been found on the scan and that they are covering bases with the antibiotics. Otherwise, in regards ***** ***** question, I'd not be worried about using these pill pockets. It is true that the first ingredient is chicken meal (so there is protein in it) but the benefit they are doing outweighs its possibly tiny impact on the diet. Especially since while using the diets is ideal, its effects are only mild for kidney cases (since they reduce workload but don't improve kidney function). So, if she were my patient, I'd have not qualms about you using this to help treat her at the moment. :)
You are very welcome,
I agree that the nurse likely is. Though we do always have to remember that while the diets are great, we need our cats to keep eating them (since eating is critical for life). So, if she ever were to go off food, you are allowed to use a commercial senior diet she likes that has a similar protein/phosphorus/sodium level (some of the Felix's for senior cats actually are similar in levels and are something I used for own kidney cat -alongside Semintra- when managing her over the years). As well, if we do have cats that go off food, we often will use those other drug treatments I noted so that we can feed them what they will willingly eat while supporting their kidneys. So, there are options to allow us to compromise with our cats and still help their kidneys.
Otherwise, I do want to point you to 2 very good web resources:
International Cat Care's page on CRF --> http://icatcare.org/advice/cat-health/chronic-kidney-disease-cats-%e2%80%93-management
Tanya's Feline CKD page (written by an owner who has been very thorough with treatment/management options) --> http://felinecrf.org/
All the best,
You are very welcome, my dear.
I am so glad I could help. :)
All the best & a lovely day to you both,
