[Enhancement] : Add Glassmorphism Effect to Pet Cards

**Is your feature request related to a problem? Please describe.**
The current design of the pet cards is functional, but it lacks a modern and attractive look. They could be more visually appealing and engaging.

**Describe the solution you'd like**
I want to add a glassmorphism effect to the pet cards. This means making the cards look like frosted glass, with a bit of blur and see-through effect. It should make the cards look more stylish and modern without hiding the content.

**Additional context**
