Dear Vicki, I have two male guinea pigs and have noticed one chews the other one’s fur. Should I be worried? Eating fur, or ‘barbering’, can upset the guinea pig on the receiving end and can even cause skin disease, so you should keep a close eye on them. Try to find out what triggers the behaviour. For example, does it happen when fresh food is placed in the hutch? It can sometimes be due to boredom, so make sure they have plenty of toys, games and extra fresh feeding hay to eat too. If the problem persists, visit your vet to check there aren’t any other causes of the fur-loss. You may also need to separate them. Dear Vicki, My three-year-old tom cat, Billy, loves a lot of fuss and attention. But he has a habit of waking us up at the crack of dawn and demands his breakfast. What can we do to stop this? Billy belongs to a group of pets that are ‘crepuscular’, meaning he is more active at dawn and dusk than during the day. As Billy probably sleeps a lot during the day, you should help him to release his energy in the evening by playing energetic games. Also, make sure he has plenty to eat before you go to bed, as a full stomach will mean he is less likely to want food when the sun rises. If he continues to wake you in the early hours don’t react to him, as giving him the attention he wants reinforces that jumping up on the bed means getting a nice meal.
