Just like yours, your kitten’s digestive system converts the food they eat to energy. If they're poorly, their tummy may be affected, with common problems being diarrhoea and constipation. If your kitten does have either of these symptoms, then it’s a good idea to get your vet to check them out.
If you see your kitten vomiting occasionally there’s probably nothing to worry about. Like all cats, they'll do this quite naturally in order to protect themselves from harmful substances. However, if your kitten is vomiting regularly, and you’re concerned for their health, then take them to the vet.
Diarrhoea can be caused by changing your kitten’s food, overfeeding, or by an infection. Your kitten should have a bowel movement at least once a day, so watch out for any changes. Diarrhoea causes dehydration, which isn’t good for your kitten. Speak to your vet for advice and reassurance.
If you see your kitten straining while they're in the litter box, they may be constipated. Like diarrhoea, constipation might be the result of a change in diet, overfeeding or some kind of infection. If the symptoms continue for more than 48 hours, it’s best to speak to your vet.
