Keep your dog or cat off the couch, away from the kitchen table or out of an entire room with our new High Tech Pet Sound Barrier Indoor Pet Barrier. This indoor electronic pet barrier for dogs and cats uses audible sound, not shock to keep your pet out of restricted areas. Receiver unit may be placed on table tops, by doors, beds, couches, trash cans or anywhere that is "off limits" to pets. The lightweight electronic pet collar sends an ultrasonic signal that triggers a loud sonic blast at the receiver unit to make your pet scat! Dogs and cats are easily trained to stay away. This ultrasonic system is superior to cheaper infrared devices because it allows people to come and go without triggering the alarm. The sonic alarm is triggered only by your pet's individual electronic transmitting collar. Range is fully adjustable from 1 ft. up to 35 ft. System includes one receiver module and one pet collar transmitter. Transmitter comes with lithium battery. Standard 9 Volt battery required for receiver (not included). Add an unlimited number of extra collars (High Tech Pet model MS-2) to control multiple pets. Add extra receivers (High Tech Pet model SBR-1) to protect multiple areas. Collar also operates our Power Pet fully automatic pet doors. Receiver is also operated by the Humane Contain model RX-10 electronic fence collar.

Two analyses were conducted to test the lethal trait‐mediated indirect effect hypothesis, and these used all nests that were exposed to at least one model species. First, we assessed if model species identity was associated with nest predation rates within the 24 h period following exposure to the model. These analyses used data pooled across years and were only conducted at the egg and young chick stages, as no such predation events were recorded at the old chick stage, presumably because at this stage nestlings are sufficiently well developed to disperse rapidly from the nest site when an approaching predator is detected (Snow ). Data were available at the egg stage for 39, 42 and 43 nests exposed, respectively, to the rabbit, grey squirrel and domestic cat models; equivalent sample sizes for the young chick stage were 30, 30 and 32. Data were analysed using Fisher's exact test. Finally, we tested the prediction derived from the lethal trait‐mediated indirect effect hypothesis that nests at which parents exhibited higher alarm calling rates and more aggressive behaviour had a higher probability of being predated. We pooled data across years and constructed logistic regression models (using 4 package Comprehensive R Archive Network, ) of nest fate (i.e. predated or not predated) and used parental alarm calling rate, aggressive behaviour, year (as a fixed factor) and nest identity (as a random factor) as predictors. Model species was not included as a predictor as this is strongly associated with parental behaviour and would have introduced strong collinearity into the model. Model selection adopted an information theoretic approach; all models contained nest identity and we constructed all possible models given the suite of our other predictor variables. We used Akaike Information Criteria (AICc to correct for small sample sizes) to calculate each model's weight, that is, the probability that it provides the most parsimonious fit to the data. The smallest number of models whose cumulative weights summed to 0·95 was included in the 95% confidence set of models, and model averaging was conducted across this set of models to assess the influence of alarm calling rate and aggressive behaviour on nest fate.

Presentations were only conducted during dry conditions with light winds (n = 68). Models were left out for 15 min and then removed. Fifteen minutes was considered an optimal period. It provides sufficient time for parent birds to notice the model, and it is within the time range during which mammalian predators typically remain within the vicinity of birds’ nests (Schaefer ) but limits the probability of habituation to a stationary model. During the presentation period, parental behaviour was recorded from a concealed location 15–30 m away from the nest. We recorded the number of 3‐min periods during which parental blackbirds alarm called. Aggressive behaviour was recorded as the sum of the number of occasions on which an adult blackbird reacted to the model by striking, diving towards or hovering within 2 m of it. All scores were summed across the male and female to give an overall metric of parental defence. These protocols follow the procedures outlined in Knight & Temple () who similarly assessed defensive behaviour of nesting birds to model predators. Each focal nest was at least 100 m away from the nearest other blackbird nest and only one male and one female were observed responding to the models; we thus assume that all observations concern the social parents of the focal nest.
Our electronic pet doors can be used with dogs and cats of all sizes.
