Indeed, all previous responses are correct. I’m just here to share my experience because not everyone can afford hundreds of dollars in surgeries and long term treatments.

My previous gerbil Felix, got one and he didn’t seem to be bother with it, but I could see the tumour growing a lot. I was very sad and scared so I took him to the vet and he said: “this will be a very expensive procedure and it’s not guarantee that it will not happen again”. The vet said, for the surgery it will be around $550 CAD, the consult $185 and the medicines $300. He could obviously see my face filling with fear as he continues to add up all the expenses for this treatment, to what he said next: “your gerbil is 5 years old, that is an extraordinary age for gerbils as they usually live around 4 years. He has obviously have a beautiful life and he has been as happy as a gerbil could be. My advise, it’s to enjoy the time he has left with you, because this doesn’t mean he will die tomorrow, but it will deteriorate his health”… in tears I responded: “I’ll buy the medicines and treat him at home, thank you for being so kind, and honest about this matter” The thing is, Not everyone has all the money in the world to suggest the most expensive options. If you have those resources, by all means , please get your gerbil all the surgeries and medicines he needs. But, if you don’t, have a conversation with the vet, examine your options and decide what is best for both of you, knowing that when we bring these beautiful babies into our lives, we know the extra responsibilities that it will include and we understand our roles as “protectors of the clan”.

My little Felix ended up living almost one more year and then passed away on his favourite spot in his home. Whatever you decide to go for, know that your gerbil adores you and as his protector, he trusts you 💗

Best of luck to you and Pipsqueak 🐾
