I’m so sorry for your loss.
You can let Tilt see Gus so he can understand that his friend has passed but he may not show any interest and is likely to already know but you can give him the opportunity. Piggies tend to know when their friend is unwell.
In terms of what to do with Tilt, he really does need a new friend. If he is only 18 months old, he can’t spend the rest of his life alone. Piggies get lonely very quickly and to spend years by himself would be unfair on him.
Whether you rehome him or get him another friend has to be your call.
While you decide what to do, the guide below will help you further.
It’s important you monitor Tilt by keeping up with his weight checks and ensure he is kept occupied with lots of mental stimulation in his cage.
Looking After a Bereaved Guinea Pig
In terms of medical advice should you notice a piggy is unwell in the future, separating them to monitor isn’t the right thing to do as it’s stressful to separate them plus you can’t watch them eat and know they are getting enough hay.
If you notice a piggy is unwell you need to switch from the routine lifelong weekly weight checks and instead weigh them daily each morning. The weight checks are the only way to know whether a piggy is eating enough hay. Hay is 75% of their daily food intake. Any drop in hay intake will cause weight loss very quickly (it can be 100g in 24 hours which is an emergency) and you must immediately step in with syringe feeding a recovery feed (and see a vet) as soon as you notice weight loss and/or that they aren’t eating.
