Typical accompanying symptoms
- Disorientation and confusion: Cats may get lost, even in familiar environments. They may have difficulty finding their way out of corners or no longer recognize the way to their feeding area.
- Altered sleep patterns: A disturbed sleep-wake rhythm can occur, with the cat being restless at night and sleeping more during the day.
- Decreased interest in interaction: Cats may be less social, withdraw from their owners, or be less responsive to petting and play.
- Changes in toileting habits: A cat may start urinating or defecating outside the litter box, even though they were previously house-trained.
- Increased meowing or vocalizationVocalization is the production of sounds that dogs and cats use to communicate. Changes in vocalization can indicate discomfort, pain, fear, or other emotional states.: Especially at night, cats may vocalize more, which may indicate confusion or anxiety.
- Decreased ability to learn new information: Cats may have difficulty learning new tricks or adapting to changes in the household.
- Loss of learned behaviors: Previously learned behaviors or routines may be lost over time.
When to see a vet?
