Question:

Vet wants us to wait till my cat is 3kgs/6.6lbs to get her spayed

I'm really hoping for some advice because I'm feeling a bit torn right now. I've got this adorable kitten named Luna who is as sweet as can be, and she's been a part of our family for a few months now. When I took her to the vet for a check-up, they mentioned she needs to reach at least 3kgs before they can safely spay her. She's currently at 2.5kgs and eating well, but I'm worried about waiting too long since she's starting to show some signs of heat. I really want to make sure she's healthy and don't want to rush things, but it's hard seeing her get uncomfortable and I’m anxious about the potential behavior changes. Has anyone else been in a similar situation? How did you manage this? Any tips on helping her feel more comfortable until she's ready? Thanks in advance!

Answer:

Hi there! It sounds like your vet is being cautious, which is great. Spaying, or ovariohysterectomy, is a significant procedure, and it's generally safer when your cat reaches a healthy weight of around 3 kilograms (6.6 pounds). This helps ensure she is physically mature enough to handle surgery, reduces anesthetic risks, and might speed up her recovery.



If she’s lighter than that now, don’t worry! There are a few things you can do at home to help her gain a bit of weight in a healthy way. Make sure she has access to high-quality cat food that’s rich in protein and calories. You can offer small, frequent meals to make it easier for her to eat enough throughout the day.



While waiting, keep an eye out for any health changes. If she starts showing signs of heat, such as loud vocalizing, restlessness, or excessive grooming, it's a normal sign of her reaching reproductive maturity. However, if you notice any unusual discharge, lethargy, or a loss of appetite, it’s best to talk to a vet straight away.



If you’re unsure about anything or just want to check in on her progress, I’d recommend booking a video consult with Dial A Vet. We can offer more personalized advice and peace of mind!

It was so easy, I needed some eye drops for my dog and thinking about going to the vet on a weekend made me nervous about the cost involved. Dial A Vet was a much simpler, cheaper option with faster results. Within 10 minutes of the call, I had the medicine I needed for my dog without an expensive consultation.

A great fast efficient service with a qualified vet who was lovely and helpful. Thank you Samantha. I was able to sort my dog at 6pm on a Sunday night for $49 - amazing. Highly recommend.

What an amazing service, at my wits end as I knew my beautiful dog had an ear infection, could not get into the vet for 4 days. Never knew there was vets online until I googled. Within 15 minutes on a Sunday I was taking to beautiful Samantha who diagnosed and treated our Jasper. Only $49. She trusted that we knew our boy and gave us lots of advice. I will definitely be using dial a vet every time and sharing with all my friends and family. Absolutely fantastic kind caring service. 11/10
