Bo here from Shopify Support!
Great looking store, I absolutely love cats so I really did enjoy looking through your store to find room for improvement. You really have found your niche which is awesome, it helps you gather the right audience which is super important, there are however some things we can improve on in this website to help you get those conversions.
While your products are brilliantly curated and your pictures look amazing you could definitely work on the descriptions. The first thing I always look at when giving feedback on stores is the product descriptions. Anyone who is familiar with AliExpress or Oberlo will spot this right away and in doing so they will know that they can get the products cheaper elsewhere. With online stores, there are no sales representatives and so the products literally need to speak for themselves. Instead of listing your products' specs in your current format you should try writing descriptions that persuade the customer to buy the item. Why do they need this cat toy? How will it make their life better? I recommend taking a look at [Oberlo's guide on writing a product description that sells here. This will also help you improve your SEO which will bring more traffic to your store organically.
Om your home page it states that you will offer a special rate to those who spend over $100 in your store. As your items average in cost at the $12 mark I would consider lowering this requirement to get discount as realistically, someone is not going to want to buy 8 items to avail of a discount. It may also be a good idea to actually display the discount code on your website as opposed to asking the customer to get in touch. Waiting for the customer to get in touch slows the whole process down and creates unnecessary work for both you and the customer. Having the discount code on the homepage will encourage your customer to check out there and then.
As your store is so niched it is perfect for influencer marketing. With influencer marketing, you would be reaching out to someone who is already well established on Instagram to get them to promote your page. Luckily for you, there are tonnes of Instagram accounts dedicated to cats so finding an influencer should not be too hard at all. You can read up on influencer marketing here.
Let me know how this goes and if there is anything else I can assist you with, I'm happy to help
All the Best,
