What to include in a question asking about changes in a pet's behaviour?:
1. The species and breed of your pet.
For obvious reasons, it's hard to give an answer if we don't even know what animal you're talking about.
2. The age of the pet.
Behaviours differ between young animals and old animals, telling us the age of the animal helps us to determine if the behaviour is normal or not.
3. What changes have occurred in your routine in the past week (or more)?
Pets like routines, they get used to routines, so it's possible that if you're seeing a change in you pet's behaviour, it could be a response to a change in the routine. In order for anyone to say for sure, we need to know what could have changed that could cause the behaviour. Even if it's something as small as getting up an hour earlier than usual yesterday.
4. If the animal hasHave they been desexed or not.?
Desexing can alter behaviour. Knowing if they've been desexed helps us to know what types behaviour should be expected.
5. The sex of the pet.
Behaviours differ between sexes of any animal. Knowing the sex of the pet helps us give a better answer.
