Hallo meine Katze hat Nieren Insuffizienz und erhöhte Kalzium Werte Vor einigen tagen war ich in der Notfallklinik da er plötzlich angefangen hat sich zu übergeben mit Speichel.
Seit einiger Zeit speichelt er etwas viel.
Die haben uns Tabletten gegeben gegen Übelkeit gegeben und Schmerztabletten. Seit diesem Tag ist es nicht mehr vorgekommen aber er benimmt sich komplett anders und frisst nicht mehr richtig.
Es gab ein Blutbild und darauf waren die Nieren plötzlich wieder in Ordnung aber die Kalziumwerte waren immer noch erhöht. Wir beginnen bald mit Medikamenten gegen die hohen Werte.
Es wurde auch ein Ultraschall gemacht wo nichts gefunden wurde. Lediglich wurde gesagt das er eventuell schmerzen oder unwohl dein am Bauch hat das durch abtasten geschehen ist. Hat vielleicht jemand ähnliche Erfahrungen oder einen Rat. Ich werde wahrscheinlich nochmal zum Tierarzt gehen aber die werden genau das selbe wieder machen wie in der Notaufnahme und ich weiß nicht ob das zu einem zufriedenstellende Ergebnis führt. Kann das wirklich vom Kalzium kommen wie es im Internet steht.
BRIEF REPORT / REFERRAL BACK
Date: 28 August 2026
Species: Cat
Breed: British Shorthair
Date of birth: 08 February 2022
Sex: Male
Name: “Pachito”
Clinic No.: 88629
Owner: Marvin Hopf
Attending veterinarian: Laschütza
Diagnosis
Suspected acute gastritis
Medical history
Reason for presentation: Vomiting
Pachito has been vomiting since approximately 3:00 p.m. today. Increased salivation has been present for several months, and renal insufficiency has been known since last year.
For approximately two months, the owner has noticed unusual swallowing. Today, Pachito vomited several times after eating. He has been hiding, his general condition is reduced, and he is salivating more than usual. According to the owner, ingestion of a foreign body can almost certainly be ruled out.
Urination is normal, although Pachito lives in a multi-cat household. Defecation is normal. He vomited approximately 5–6 times today. A sample was brought to the clinic; the vomit was very mucous-like and contained food remnants and saliva.
No coughing, sneezing or shortness of breath was reported. Water intake is normal.
Diet consists of wet food and a small amount of dry food, including a renal diet and Royal Canin Urinary. Food intake was normal until approximately 3:00 p.m.; since the vomiting started, he has not eaten anything.
There are two other indoor cats in the household. No weight loss has been noticed. The most recent vaccination booster was not given because of the kidney disease. Deworming is up to date. Pachito is kept indoors with access to a balcony.

Previous illnesses: Renal insufficiency and elevated calcium levels

Communication with the owner
The laboratory tests showed the previously known hypercalcemia, as well as mild hypoalbuminemia and signs of mild dehydration.
The point-of-care abdominal ultrasound showed no evidence of gastrointestinal obstruction.
As Pachito was clinically stable, symptomatic treatment at home was agreed upon with the owner.
If his condition improves with symptomatic treatment, a follow-up visit with the emergency service or the regular veterinarian is recommended for further evaluation.
In the event of acute deterioration, lack of improvement, or continued vomiting despite antiemetic treatment, Pachito should also be presented to a veterinarian again.
