Here are some tactics and platform features that are best suited for discovering and engaging influencers in the pet care industry:

1. Demographics and Interest-Based Filters: Use influencer marketing platforms that provide rich audience demographic and interest data. Brands are able to filter influencers based on their follower’s interests and demographics. For instance, if you’re targeting pet owners, you might look for influencers whose audience are predominantly interested in pet care or animal welfare.

2. Content and Sentiment Analysis: Platforms like Flinque provide content analysis features that allow brands to assess the relevancy and sentiment of influencer content. You can use these tools to locate influencers who consistently produce high-quality, positive content about pets.

3. Geo-Targeting Feature: For local brands or events, platforms that offer a geo-targeting feature can be beneficial. You can discover influencers who have strong following in your target geographical areas.

4. Performance Analytics: Insightful analytics related to an influencer’s engagements, reach, and ROI can help in making more informed decisions. For example, an influencer might have a moderate audience size, but extraordinarily high engagement rates, which could be more valuable for certain campaign goals.

5. Partnerships and Affiliates: Leverage platforms that offer partnership or affiliate features. This can be an effective way to build long-term relationships with influencers who have a strong connection to the pet care industry.

Remember, the best platform is often dependent on the specific requirements of your campaigns and the target audience you aim to reach. It’s important to consider, align, and balance these factors when choosing a platform and planning your influencer marketing strategy.
