What matters most under 50
At a tight budget, an electronic pet door is unlikely to be fully featured, so focus on the essentials that actually work. Electronics mean it cannot be organic, but you can look for a responsibly made unit with a decent seal so you are not paying later in lost heat. A simple collar tag reader is more affordable than advanced microchip systems.
Under this budget, check the flap seals reasonably against draughts, the locking mode is secure, and the battery life is realistic rather than needing constant changes. Measure your pet so the flap fits properly, since a cheap door in the wrong size is wasted money. Read how it handles power loss, as some lock shut and some stay open. Fit it carefully following the template. Train your pet gently with treats so they trust the flap, which matters just as much as the price you paid.
