The Alivo is a Shimano brand. If you go to eBay and type in "Shimano Alivo 7 speed rear derailleur" not much shows up. I guess the lower priced bikes have all gone to Shimano Tourney as that has a lot of hits.
If you want to be certain your existing indexed shifters will work with the new RD, buy another Shimano RD. You need to observe whether the RD is direct attach (see here: Shimano Tourney TX35 6 7 Speed Rear Derailleur Direct Attach | eBay) or uses a built in hangar (Shimano Tourney TX35 6 7 Speed Rear Derailleur w Hanger | eBay) Look and see the length of the cage on the RD. They come in three kinds short, medium, and long. Which you need depends upon the range for the new rear cassette. If you simply replace the existing cassette with the same size, buy an RD of the same type as you have now. SRAM and Shimano cassettes are interchangeable on your existing freehub. It helps to have a chain whip to hold the cassette while you remove the outer ring that holds the cassette to the freehub. Of course you should use a Shimano cassette remover. Using the right tools makes the job a lot easier.

So, you don't mention why you want to change your rear derailleur and cassette. Are you looking to upgrade? Are you looking to change gear ratios? Are you replacing worn/broken parts?

If you're simply replacing worn/broken parts, you could even use a new, current Alivio 9 speed rear derailleur with your 7 speed cassette and shifters. Here's the current Alivio rear derailleur:
RD-M430-L

As mentioned, any SRAM or Shimano 7 speed cassette should work. You really ought to make certain it actually uses a cassette instead of a freewheel, as the Panasonic Mountain Cat is potentially old enough that it could possibly have a freewheel instead.

Perhaps you could provide us the inspiration behind why you want to replace the parts. That might lead to more useful advice in responses.

I wondered how you got a Panasonic bike with Shimano Alivo components on it since Panasonic quit exporting bikes to the US in 1989and the US Panasonic bikes would have different components. Your location in Pakistan explains why you might have a newer model with these components as the company continued to sell bikes elsewhere. Americans who own the older Schwinn models that say "Made in Japan" and are stamped with "Schwinn approved" on many of the components actually bought Panasonic bikes relabeled Schwinn. Of course you could go to another bike shop and buy the same bike with the Panasonic label and save about 30% over what Schwinn sold them for!

If you can use eBay, the derailleur mentioned by a previous poster is available on eBay from China or Taiwan with free shipping for a bit under $40. I'd suggest buying it from China or Taiwan, not the US as most US suppliers are going to hit you with some pretty exorbitant shipping costs for a product made in Taiwan or China and sent here. Here's one that ships to the Philippines for free. Shimano Alivio M430 RD M430 Rear Derailleur 9S MTB | eBay If the RD is in decent shape but the jockey wheels are worn, you might consider buying just the replacement wheels. As long as the number of teeth match, these should work: Bike Bicycle Derailleur Guide Pulley Wheel Accessories - US$2.99
