Symptom: Straining to Urinate - When Should I Contact a Vet?
Straining to urinate means your pet is having difficulty passing urine. Being unable to pass urine is a life-threatening emergency, particularly in male cats, and requires immediate veterinary attention.
Common signs include:
Frequent attempts to urinate
Passing only a few drops of urine, or no urine at all
Straining or squatting for prolonged periods
Blood in the urine
Vocalisation, crying, discomfort or excessive licking around the genital area
